Premades Ruining Game For Solo Players

Guys.. bring back SoloQ at last. Game experience turned into complete bs in Dynamic. 3-4 premade: Zero communication (not even pings), doing whatever they want, flaming when you politely ask to speak english, flaming if you ever try to call objectives, reporting altogether if they don't like you - as a solo player I get this 80% games (thats probability of 3+ premade in your game now). Yea I understand this is fun for them, because they talk through teamspeak and feel fine - for me its waste of time or even worse. The only 'good' premades are those without teamspeak-like setup - and this is very very rare occasion. I want to remind you that mechanics are not only fun of this game. Communication is the big part too.

Ye I understand splitting into 2 queues could hurt waiting time for high ranks. But you can do it only for pre--diamond - it wouldn't hurt times at all. Diamond+ are 1% of players or less right?
