Players demanding more bans is indicative of the games terrible balance.
There are just way too many champions that are overwhelming, or just flat out broken, for the game to be balanced. Season 6 is quite the nightmare. It is no longer about who is better, its about who can secure the most "power picks," this is even true in competitive. Its laughable that Riot can claim to run a sport when the playing field is this skewed.
Give us more bans, or at the very least, balance the game so there aren't so many champions that REQUIRE a ban.
