@People Asking to Remove Blind Pick
Don't.
It's the mix between casual and competitive. While it does induce trolls, so does every other game mode. The numbers may alter, but Blind Pick is a mix between the pure casual clownfest of ARAM and the rotating game modes as well as some competitive aspects of ranked/draft.
Think of it like a spectrum, with the polar left being the RGM (rotating game mode) and the polar right being Ranked.
It's there for the variety, and in a game like LoL where you must invest a lot of time and play a lot of games, you need variety.
Don't remove blind pick, don't remove Twisted Treeline either.
Don't let it be another Dominion.
(That's not to say we should remove Normal Draft, that needs to be kept, as it is on the middle-right of the spectrum; support Normal Draft, but be wary of the importance of Blind Pick to others, even if you do not like it)
