ranked bans, item bans.
on top of champion bans, you should allow item bans as well. the new items like duskblade or even some items like maw really break the balance of the game, when an ad assassin turns into a tank, it gets stupid, assasin should be a kamikaze unit, yeah he will get his kill, but he will die doing it. if he face checks a bush vs an ap assasin he should die, you shouldnt have an absorb shield that pops up and saves him so he can then burst you down, he should be punished for being reckless. and if your going to bring in an item like duskblade then you need to have accross the board nerfs on any champion who can take advantage of it, to compensate for its dmg output.
