Hi, I think we don't need more than 6 ban actually but the draft mode most be changed, its overdate. I don't know how that system is like on other game, but I think Riot should take for example the Dota 2 system.
Because in soloQ, when the first pick ban the counter of his favorite champion instead of banning powerful champion, it's very annoying.
Moreover, it will be more strategy in competitive match, and maybe more champion can be used during those match.
Sorry for my bad English, it is not my native language.
