4 man premade will destroy HIGH elo play on solo queue.
It's already pretty hard to find a match once you are challenger on solo queue ( I am challenger on the brazilian server ). But with 4 man premade it will not only be harder to find a match, but will make solo queue at high elo pretty unbalanced. Teams will basically queue up together ( except one, but it doesn't matter ), making the game very unfun. Please, duo queue is already a hell do deal with, don't make it even harder with 3-4 man premade.
