Tier Shift

[MaestroDeSWAG]

I feel like it needs to be pointed out almost all of those (including one or two of the Bolds!) lose 100% of the time after rocks and an SD. Neither of those are particularly unrealistic conditions, either, as rocks are, well, rocks, and Pinsir forces out quite a bit even neutrally.

None of the bolds lose to rocks and at +2, rotom h ( the one who takes the most from rocks) survives a close combat and ko's back with volt switch or overheat. At +0, it's only a 1.8% chance to 3hko, and usually pinsir isn't going to want to throw around CCs, for fear of the defense drop, so it can almost have a guaranteed safe switch in. If you switch. In as it boosts, there is a very slim chance that you'll be ohkoed, but a better chance that pinsir loses. Also, mega mane makes his life difficult by keeping up momentum and seriously denting, If not ko-ing it. Plus, since we're discussing rocks, let's not forget that pinsir loses 1/2 it's hp upon a switch in with rocks up. This can prevent it from becoming the monster you speak of quite easily. You need some serious hazard support for it to work, which sacrifices momentum. You have magic bounce, but 3 of 5 bouncers aren't available, since you are running pinsir as your mega. So, it's not the beast you seem to think, imo.

Edit: don't get me wrong, it's a monster, for sure, but it's just not this unstoppable force that will destroy your entire team with 0 support.

I'm not overly worried about pinsir, and my interpretation of what the mechs are supposed to be is that it recieves +5 stats (this is what makes most sense as well for balancing other megas too). 110 speed is still not game breaking even with a +2 quick attack to take out some of the faster stuff. Plenty of defensive counters/checks as well. One thing that does worry my though is Wobbuffet.

205/48/73/48/73/48 Thanks to shadow tag being banned in the lower tiers wobbuffet has dropped to PU. This gives it the bulk to trap the majority off offensive mons, especially revenge killers. I've seen a few teams using it on HO, idea is you set up something like a Terrakion and force you to bring in your revenge killer. They just out switch to Wobb and likely aren't even 3hkoed, leaving them free to sweep later. At worse it forces a 50 50 against offensive if you have a boosting move since encore. This leads to it getting two possible kills one of which is probably devastating for your team. Also custap berry is legal again so destiny bond adds further annoyance. Finally the extra speed means you can ev it so encore can actually hit a defensive mon first which makes it more useful against stall.

Anyway just thought I'd float this here first so everyone can see it, maybe I'm alone in my views on this one though.

I like the idea of wobb... Sounds pretty evil.

However, where are you getting your information concerning the boost? The op very clearly says the exact opposite. Whatever your oppinion on it, it doesn't matter. It is meant to provide the boost reliant on the base form, so when you say "at least that's my understanding," I am frankly thoroughly confused. What has led you to this?

 

[Talpr0ne]

I recall this being decided in early ORAS to prevent Lopunny and Gallade(at the time in RU with the mega in BL) from being overpowered, which is the exact same situation we now have with Medicham and Pinsir.

Then the op needs updating

That's nice to know. Do you know where I can find that? It would be nice if it were common knowledge.

Tier Shift Suspect #2: Pinsirite

As many of you are aware Mega-Pinsir is now no longer OU and has dropped to tier BL and now receives a +5 boost to all its stats. With that minimal boost it has become a force to be reckoned with. Its sheer power allows it to overwhelm many Pokemon, and its Speed is decent by TS standards. Not to mention its access to powerful setup moves and priority. So the Council has decided to suspect Pinsirite. Discussion should be focused on Checks and Counters, and how viable they are in the meta. Also discuss on how Pinsir is the same or different as the OU meta. Your posts will be important to the outcome of the suspect, quality of argument will heavily influence voting. As with before the Council will have the final decision.

OM room's discussion on the suspect at hand.

My opinion, which I made as obvious as I could earlier in the thread, is to ban Pinsirite. Pinsir's combination of very high stats, good movepool, boosting options, and priority make it simply too centralizing for Tier Shift. The few things that can RELIABLY COUNTER it often times end up being niche and otherwise, unviable. There's a small handful of relevant tier shift mons that beat Pinsir, and for that reason it needs to go.

And before someone mentions hazard weakness, it's honestly not going to be relevant 90% of the time. A smart player, when hazards are up and theres no clearing option, is going to send it in when it forces a switch anyways. It will rarely ever have to live a hit if played well.

 

[Chopin Alkaninoff]

This post pretty much summarizes the most of Pinsir checks and counters.

If it is supposed to get +10, I would agree with suspecting it and it would probably be banned. But it isn't programmed to be +10 yet, and I don't know whether it is supposed to be or not. At the moment, it does have a few other pokemon that do as well or better against it than what you listed.
I'll also list some that do somewhat well against the standard jolly set. Some of these would be rendered useless against earthquake, but generally close combat is better coverage. Also not calculating them at +2, since it is about double the amount.

As you probably guessed, the bold ones are the better ones at beating pinsir.
That's not even including things that outspeed and kill, barring scarf landorus-t and manectric.

Also, rocks weakness is relevant, because it limits the amount of switch in and getting your pokes picked one by one. Imo, Mega Pinsir is the same as OU, just with a little more bulk. It just seems stronger because most of its counters and checks are in OU while people tend to use lower tier pokes here. I'm leaning towards no ban for now.

 

[Kit Kasai]

I haven't played tier shift in a long time, so I have no idea what the state of the meta is, but I'd like to ask for clarification on a few things.

What exactly makes Pinsir so much better in TS than it is in standards? To me, +5 stats barely make a difference. IDK about TS speed tiers but a cursory glance at the mons in BL/UU/BL2/RU says that there is nothing really relevant to outspeed. The +5 atk is barely noticeable, as it's only a 2.4% increase in damage. In my opinion, Pinsir's standard counters should work perfectly fine in countering it. Zapdos is still a perfectly viable and reliable counter, and there are many other less reliable counters such as Skarmory, Rotom forms, Mega Aggron, Rhyperior. There are also many viable checks, including Raikou, Rotom Forms (offensive variants), Manectric Mega, Aerodactyl Mega, Hippowdon (at +2), Landorus-T (at +2), basically any fast Electric type, etc.

To me, Pinsir isn't a case of being OP rather it is a case of being antimeta. It really doesn't gain much from TS and its boosts theoretically shouldn't push it over the edge. I think the meta is just simply unprepared for it and for some reason isn't running the proper counters.

I'm gonna edit the rest in at not Midnight, but I feel like you're getting the point. Even though some of these mons "wall" pinsir, they're often times unviable/niche (Stunfisk) and lose anyways due to lack of power.

The problem isn't really the OU mon's inability top counter it, more their viability in Tier Shift most of the time. Zapdos is honestly not good by any real standards aside from beating Pinsir (you can even see this in OU, as it's declining in viability as birdspam goes away). While quick Electrics are good revenge killers, they have to get in for free, especially since they're often times frail. Switching in outright often times gets them killed to the Return + Quick Attack combo. Aerodactyl also suffers of this. Me and KS calced, and Hippowdon cannot win, even with Rock Slide (and only a little of the time with stone edge).

(Edit)Sorry for double post but I wasn't waiting all night to say this

 

[Chopin Alkaninoff]

Pinsir has counters, yes, but even if it doesn't have counters, there are another questions that defines a poke OP or not.

Does it make the metagame unhealthy?
Does it single-handedly ruin playstyles?
Does it make pokes unviable?

I don't think Pinsir fits yes to the questions above. Greninja single-handedly ruins offensive and balance playstyles, while Aegislash make pokes unviable. I don't see how Pinsir fits most of the above questions.

Does it make the metagame unhealthy?
Every team being absolutely forced to run something to beat it or lose at team preview is unhealthy in my opinion, but I assume you can say that for many pokemon, so I'll go on to 2 & 3

Does it single-handedly ruin playstyles?
Frankly, yes. Hyper offense is fairly ineffective vs it, as it's powerful priority can often times kill common HO mons outright. Scarf electrics aren't too hard to fit in these playstyles, but that's a bit limiting, as your scarf mon is gonna be this type guarenteed.

Does it make pokes unviable?
It's much more of a liability to use anything weak to flying now, as they'll obviously die like nothing.

and one you didn't mention that I think is important:
Does it make the metagame less fun?
This is something LC has that I think needs to be applied to any suspect argument. Pinsir simply makes Tier Shift less fun. You're just switching from your wincon to a Pinsir counter, it makes it almost an algorithm to play. Not to even mention it makes more quick paced playstyles garbage often times.

I'm gonna edit the rest in at not Midnight, but I feel like you're getting the point. Even though some of these mons "wall" pinsir, they're often times unviable/niche (Stunfisk) and lose anyways due to lack of power.

That's a lot of calcs that I don't want to take the time to read, but I'd like to point out that, while I don't completely disagree, some of your scenarios are stacked in Pinsir's favor, and you miss certain little nuances that are actually really important to point out. For example, if pinsir hits Skarm w/ a +2 CC, the defense drop will put you in KO range with just a little prior damage. At -1, it only requires at least 13.6% damage for Skarm to OHKO it w/ BB. This could easily come from just switching in on a resisted attack. Also, if you're running BB, you're not gonna run a -Atk nature. W/ a neutral nature, pinsir only needs to take 4% damage for Skarm to secure the ohko. Thats one turn of toxic damage. Also, Skarm could just roost and tank the hit to lower Pinsir's def, and then you secure the ohko for sure once it's been lowered twice. Even at +2, it's only up to 61%, which is only slightly more than roost+ lefties recovery.

Announcement: BLs now get boosts from the tier above instead of below. Due to changes in the boost mechanics, Pinsirite is no longer being suspected. Do to those same changes, a council will no longer be necessary and the current one will be disbanded. If the need arises for a suspect, a council of 5 will be formed out of active players who understand the current metagame. New thread has been posted here as well.
