I've been playing LoL with a premade group lately. Usually 4-5 of us queue at once and I find that it's waaay funner that way. When we lose it doesn't bother me, and when we win it feels even better. Solo queuing is just unbearable now after playing on vent with a premade for 15 or 20 games in a row. Hell even queuing with 1 friend and 3 pubs still sucks.
BTW when Twisted Treeline goes into MM it's gonna turn this game on its head. I can't wait.
