GRIPE, doesn't begin to describe what I think is the problem...
Yea maybe you shouldn't ban the best stuff but then again... lemme "paint you a picture". This is gonna be a big one so it'll be hard to ignore.
Let's assume Mega Heracross specifically is banned. Who's the next strongest pokemon? Deoxys Attack.
Deoxys Attack is very powerful, don't get me wrong. It's also very fast on top of this. But the downside is that, it's incredibly frail. 50/20/20 bulk is absolutely ABYSMAL bulk for anything. Though, I feel the trade off for this extreme bulk deficit is worth 180 offenses and 150 speed. Compare this to Mega Heracross with 80/115/105 bulk, AND 185 Attack. His speed being 75 isn't even all that bad either. Why use Deoxys Attack when Mega Heracross is not only stronger, but bulkier -- and still has a good speed tier? If we look at the second strongest pokemon, it's a 3 way between Rampardos, and 2 Megas in Gallade and Banette. Each and every one of these have some form of restriction added to them, though it is not obvious at first. The bulkiest of them is Mega Gallade at 65/95 -- which compared to Heracross anyways, is not bulky at all. Furthermore, Rampardos has a paltry speed stat of 58 -- so it's most likely moving last safe for facing a team with Ting-Lu exactly. Mega Banette seems fine compared to the 3 with it being the same speed as Heracross and all (plus Ghost type), but again, not nearly as bulky as Mega Heracross, AND is weaker by a very substantial 20 base Attack. After 165, the next highest is Mega Pinsir at 155, and from there, it gets lower and more moderate to handle compared to the other things. The difference between Mega Heracross and the other things after it is that IT'S SUPPOSED to be manageable due to "Bug-Fighting being mediocre defensively". This is absolutely not the case when you add on terastallization -- giving one of the very likely 2 Mega Heracross you're staring down a lot more staying power than necessary. Then add on the Defiant/Intrepid Sword, and the Choice Band and all a sudden, this is not a fair fight. 1 good physical attack and you're getting domed for ~20% at the bare minimum.
We can also look at this from a defensive lens if we want to. Take Ting-Lu is the example. 155/125/80 is absolutely amazing bulk even without Vessel of Ruin, and base 110 Attack for most walls is actually VERY high. Now, again, let's compare this to say... Regirock.
Now, Regirock is incredibly bulky. 80/200/100 is absolutely superb bulk, and 100 Attack baseline doesn't hurt either. And of course, Rock being a very interesting double edged sword. For a Normal resist (very important), you gain 5 types to wack you for super effective damage, which honestly? I'd take that trade off. It means I can run a nasty Weakness Policy set and absolutely fry everything. Other mons like Avalugg with their 95/184 physical bulk, Great Tusk with 115/131 bulk being comparable to Ting-Lu, and other things like Mega Slowbro and Cloyster all being very equally physically bulky doesn't mean that Ting-Lu should be any better. Heck, Rhyperior and Glastrier are both STRONGER than Ting-Lu. But the issue is the very reason they are so bulky: the typing. Safe for terastallization, you're stuck as mostly a Ground, Rock, Ice, or Water type if you wanna be physically bulky, or you have comparably low special defense as the downside. Being slow doesn't exactly matter here, but it can come up against something like Mega Heracross or Ampharos. Similarly to Mega Heracross, Ting-Lu simply gives you everything you need and more. Why is Avalugg as a risky physical wall who needs terastallization, when you can have Ting-Lu -- who doesn't need to [but prefers] their tera, and can accomplish nearly the same task on a very similar power level (quite literally actually, they have almost the same Attack stat). Bulky on both sides, physically stronger than most walls, can run Weakness Policy to take advantage of its 6 weaknesses (I don't know why it's got 6 either). Ting-Lu just puts everything else to shame compared to him.
And of course doipy hooves, the icing on the cake: FLOWER VEIL AND TOXIC CHAIN.
These abilities, as well as Defiant and what have you on specific mons, is absolutely bonkers. Toxic Chain CALLS FOR YOU to have an answer to it, and while most teams do, simply the threat of Toxic Chain softly forces you to answer it. One of these answers is, Flower Veil -- which in itself is also obsurd. The ability to ignore all status conditions is fine. Who really enjoys getting paralyzed or frozen anyways. Ignoring stat changes is also fine. Defiant and Competitive are in part strong abilities as a way to abuse the multitude of ways your stats get dropped. Having BOTH OF THESE, with a type that can VERY EASILY ABUSE WEAKNESS POLICY for a +2 in both offenses... suddenly things are looking very, very bad. The ease in which you can get a free +2 in your offenses with little to no drawback should be downright illegal. "Mirror Herb", they said. To which the Mega Venusaur proceeded to use HARDEN before the Weakness Policy proc'd, and then followed this with PRISMATIC LASER. You're dead. This didn't actually happen to me, but, it's not unlikely your Mirror Herb outright fails because of the RNG (which is a very important factor in why so many abilities that see play are good).
I can go on and on about the little details and contingencies with every single thing I find problematic (that is not bias, and is consistent and persistent), but I (if anything) propose a solution:
SETTING STANDARDS FOR WHAT IS AND IS NOT ALLOWED
Ready your pitchforks if you dare, but I firmly believe there should be a known precedent for good and wrong. For example: X pokemon should not exceed ... bulk if it has ... Attack or more. Or X mon with ... bulk should have less than ... SpDef. One of the plus side to even playing this tier that I believe makes it fun is that THEY HAVE GENUINE DOWNSIDES. I love having to challenge myself with my quirky Mega Sharpedo knowing it's at a disadvantage, or my Mega Camerupt before unlocking his true potential (before it became a mainstay). My Ting-Lu should not be allowed his cake and be able to eat it, and neither should my Mega Heracross. As I said in my previous post, the top 10 has barely changed over the last few months. And this tier has been around for maybe, 5 years at this point? On a personal level, I would propose a suspect test, a community poll on what the people think is a problem with this tier. I like this tier and will always support it man, but sometimes we need to see change. Change that happens once every 4-ish months is not change. It is a small glimpse of hope before the realization of your terrible situation hits you. I trust you doipy, or anyone else involved in this tier, will help salvage it. Please.
(Also doipy I'm sorry if this comes off as rude towards you. I'm not trying to purposely call you out, I'm not trying or demanding anything. I just want you to hear my piece on what I believe is the issue.)
