For the record, I'm against banning stealth rock right now simply because I agree that there isn't enough time yet in B/W2. You also have to consider that stealth rock's mechanics could be changed in X/Y. It seems pointless to ban something when the next gen is so close and we dont know what will happen to said suspect. That said, there is one argument against a suspect test that I'd like to dismiss. Only moltres/Yanmega are affected by SR: This actually isn't true, though they are the most obvious cases. Fire/Flying/bug/ice. Those are the types most affected by stealth rock and any Pokemon from those types can go down a tier just because of stealth rock. Moltres, victini, Darmanitan, Arcanine, and the event Entei are the major examples of Fire types that may go up a tier if stealth rock weren't around. As for ice types, Kyurem-b, (I know it's OU already but think of how much more powerful it would be if Stealth Rock weren't around. It might be suspect worthy) Kyurem, (It's normal forme) Weavile, Frosslass, Abamasnow, and Walrein (maybe). For Flying types, Staraptor, Honchcrow, Crobat, Zapdos, and Togekiss. Admitedly, I dont have very many for bug except Yanmega, maybe Galvantula, and maybe Heracross. Those were just off the top of my head mind you. If we did ban stealth rock right now 3 pokemon would have be called suspect worthy right now (Dragonite, Volcarona, Kyurem-B.) but 18 different pokemon would have a shot at being OU. That's not even mentioning ALL the pokemon that dont have a chance at becoming OU but are held back at going up tier of their own or pokemon that can actually tank some big threats in OU but are held back by that 12% every time they switch in. We dont know what kind of metagame a stealth rock less metagame is. We do know that there are pokemon that are being held back simply because of stealth rock. We may not have time to ban stealth rock before Gen 6 comes around but consider this. If gen 6 comes around and stealth rock is still what it is now, it'll become the gen 6 metagame as well.
