Six isn't enough. The game has around 120 champs, and then you expect six bans to suffice?

Like I said, a lot of people don't get the point of banning champs. The way I have always seen it, you are supposed to ban problematic champs to help aid your strategy (e.g. you ban Janna because you are going to run Fiddlesticks for your team comp).

However, because the game only gives three bans for each side, these types of bans are tough to come by because you just end up choosing FotM/OP champs with these limited slots. And this is why the same batch of champs always see bans, which makes the banning exercise rather moot in a lot of cases.

Riot might as well ban champs like Blitzcrank and Thresh in ranked games, and it would be the same effect.

In short, more bans are needed. Plain and simple.
