I'd argue that although all hell broke loose when Genesect was released, it was because it made abusing the already broken aspects of the meta (weather) much easier.
How is weather in general broken? I can understand if your complaints are primarily Rain-oriented, but in all honesty weather playstyles compose the entirety of BW OU, and BW2 OU as well.
In the past, in fact, Sand was a particularly common playstyle and Tyranitar/Hippowdon were not banned to Ubers despite sharing a very powerful ability which helped shape DPP OU to being one of the most balanced things ever. Hail was secondarily common, and Abomasnow is a good Pokemon in its own right (it was forced out of DPP UU, and was still a decent threat in DPP OU).
Weather is no longer the authoritah of B2W2 OU, because Genesect is decimating all in its path except anything faster than it. With a Choice Scarf, that almost always just means other Scarfers.
Gene simply isn't good enough in and of itself to singlehandedly cause the massive pile of shit that the meta has devolved into since its arrival.
Actually, it is. Running a weatherless VoltTurn team is way too easy with Genesect and Rotom-W hopping back and forth, making some Pokemon's lives hell. With hazard support from Deoxys-D (and Roserade, because my team is also a Dark Horse like always) and Pokes dying left and right to hazards and otherwise-2HKOs, weather is becoming less and less of a problem for me, and other VoltTurners actually do not care about Rain.
Weather is no longer the authoritah of B2W2 OU. However, this is exclusively because some things have changed.
Correlation =/= causation and all that.
I'm not precisely certain what this statement has in terms of relevance to anything. However, this phrasing is very unusual for me to witness.
It's clearly Suspect material, no argument, but my experience playing against it where neither weather offense or Deoxys-D are involved is that it isn't as massively unhealthy for the meta as it seems now.
One's experiences alone do not constitute saying something is(n't) unhealthy.
I myself have played with and against Genesect - it single-handedly assumes direct control of the match with little effort. And I run a Rain team myself, which is indeed weather offense.
I've also had experiences which, by contrast, prove Excadrill to be largely underwhelming. I then ran into some Focus Sash Exca sweepers and was proven wrong, despite my Stoutland doing a decent job of sweeping himself.
Oh yeah and X-5 you're getting your I's and your T's confused =P
/agree
Counterarguments above in bold.
And now for me to propose Suspects; most of this is in agreement that Deo-D, Torn-T, and Genesect are bonkers and need to go:
1. Deoxys-D - There's a lot of agreement here that Deo-D's capabilities with hazards are a lot more supreme than other hazard setters. In no small part, Magic Coat and Recover help keep Deo-D alive while it doesn't get OHKO'd. It also has no trouble dealing with Starmie and Tentacruel thanks to Electric Gem-boosted Thunderbolts.
2. Tornadus-T - On an alt, I run Torn-T as part of my weatherless VoltTurn team. Regenerator helps it way too much with U-turn - something slow that threatens to OHKO Tornadus-T will instead wind up being walled by something else.
That said, a lot of people also agree that it is a prominent threat in Rain, although this is also a lot to do with people not using Abomasnow to not only hard counter Rain, but revengekill Tornadus-T. Weather wars are to be won, not complained about in a defeatist manner.
3. Salamence - Moxie MixMence has been mentioned as requiring prediction to win, and prediction alone. That said, it wins too many games too easily. Revengeing it is literally the only way to attempt to kill it. If it's a Scarfed Moxie MixMence, good luck. After a few Moxie boosts, not even Heatran is going to wall those Outrages.
Something that lacks counters and fuels this perception of "Stall is dead, stall is dead, neener neener neener" needs to get the hell out of B2W2 OU. I will not give up on this being Suspected.
4. Genesect - There's enough conversation about him to fuel several billion Suspect Tests of him. He benefits from the weather which once kept BW OU in a state of relative balance, much like Tornadus-T and others.
He also overcentralizes the metagame, as already people are using stuff to counter one Pokemon as opposed to one playstyle.
Let's use Rain as an example of a playstyle. Since it's a weather, one just needs to change the weather. Politoed is extremely easy to counter thanks to Abomasnow and Celebi, among many other Grass-types who can sponge attacks from Toed, while otherwise laughing in the frog's face, and then promptly winning the weather war thereafter.
Now, an example of a Pokemon that was recently banned, whom people still want to see return despite even my saying "HELL NO" - Blaziken. To counter it, you needed stuff that didn't wind up OHKO'd to death by its attacks. Slowbro and Jellicent among a few others were cited. To escape those guys, all Blaziken had to do was Baton Pass out of there with its boosts to something that said "Problem, Bulky Waters?" and then swept. Not to mention Blaziken can do some sweeping by himself which also caused him to be banned from Dream World OU.
After that, though, I am out of Suspects to propose. Mostly because I don't genuinely believe Jirachi is broken when he is statusable, and OHKO-able by the likes of Garchomp (who is actually somewhat fun to use, albeit not as easy to counter as others claim; that said, even Chomp has a few checks of whom I rarely see - if any of you want Garchomp to not be on my list of "I will not give up until this is put back in Ubers where it belongs" things, I would strongly advise Weavile among others).
