Banning Baton Pass is stupid as all hell. Not everything with Baton Pass ends up being broken, which proves that Baton Pass isn't broken in of itself. Taking away not-broken options of certain Pokemon is ridiculous. You're nerfing Ninjask et al. for absolutely no reason. I don't care if it's "easier" to ban Baton Pass instead of its potentially-broken users. All you're doing is basically taking a broken Pokemon and banning one of its moves to try to make it viable. It's that whole "let's try banning Dark Void instead of Darkrai!!!" shit all over again.
If a Pokemon is broken when it uses a certain set, ban the Pokemon.
