As a solo queue player... I'm sick of having to play against two people the entire game.
Having a jungler who's queued with ANYONE on their team is an absurd advantage, and shouldn't be matched against a team without a queued jungler, period.
Just ran into a trio queue, as far as I'm aware nobody on my team was queued together (they were flaming each other in chat), the communication between jungle and mid/top pretty much won them the game, Hecarim chain ganked me and set up 4/5 man dives bot. The coordination is simply impossible to match as a solo queue player.

Looked up the laner I was against after the game, he was bronze last season, he had 6 games (all wins) with a guy that wasn't in the game, looked that guy up, he's a Hecarim main, boosted this guy out of bronze and into silver, and switched accounts to continue boosting him...
