I'm having trouble with the idea that Stealth Rock is broken simply because it is used all the time. Things like Toxic are used on almost every team too, but we wouldn't ban that. I know the two aren't comparable, so please don't point out that that was a weak analogy. The point of this is what makes something broken? I believe that a thing is broken iff it causes people of greater skill to lose to people of lesser skill a majority of the time, or at least lessen the gap between them to the point where matches become a tossup. I would say that very rarely are matches decided by who gets up Rocks first (I say rarely, because it is obviously possible for this to be the case, just not commonly). When Genesect was running around, matches became "who can set up Rock Polish first?" and when Excadrill was around it was "who can set up Swords Dance first?" but this isn't the case with Stealth Rock. Basically, a new player that has Stealth Rock doesn't have an extreme advantage over a veteran who doesn't. Yes, it is an advantage, but not one that puts them on an even playing field, in my opinion. That is why I said Stealth Rock isn't broken. It is a staple of OU, and it causes a lot of Pokémon to be considered less viable than others, but it's affect on the metagame isn't inherently negative. It makes some Pokémon good and some Pokémon not good. But it isn't on the same level as, say, Drizzle or Drought (which I do think should be suspected) when it comes to the support it brings. That's just my two cents.
I think it's easy to underestimate how influential SR really is in any individual match. Let's say Person A gets rocks up on turn 1, but Person B only gets rocks up on turn 15. In the course of 15 turns, Person B has likely switched 4-6 times. That's about 50-75% (not taking into consideration weaknesses or resistances) worth of damage spread out that Person B has taken that Person A hasn't, simply from switching. It's a bigger determining factor than a lot of people are giving it credit for.
My question is what's the point of banning SR when it will hurt OU in the short term rather than helping it?
BW2 has about 5 months left in it so there's really no point in banning it when things like Volcarona and Dragonite will become broken and just fuck up the meta. If you wanted to ban SR this topic should've been brought up like 2 years ago, it's a little late. Can we not just wait until Pokemon XY to address these issues?
I addressed this in an earlier post.
