Let's get this out of the way here, I'm not pro-SR. My point was that, the way we've set up ban lists, Stealth rock can't really be banned under anything we've done before (although looking at this now, I suppose trying something new isn't taboo). My argument was never a question of balance, but more one looking at precedent bans and comparing it to that. Also, I don't want move tiers either, I'm just saying that if we start banning moves, it's not unthinkable that something could happen (though that's not really a great argument).
Icecream brings up an interesting point, though. BW was based off of Stealth Rock. Most of the OU meta deals with it well, and those who don't are either rejected or can somehow compensate for it. A ban would certainly change things up, not post-Genesect change, but like new generation change. I'm thinking that it might be interesting to get a suspect ladder going, just to see what a Rockless meta would look like.
