Exactly. Everyone playing on Summoner's Rift takes themselves so damn seriously. I think there's just something about the map which causes a lot of stress and frustration - you play in your little cubicle-like lane for a dozen minutes, being mostly isolated from your teammates, just competing with your opponents. But eventually you're forced to work together with your other teammates and compete against their respective lane opponents, and I think that transition can be pretty rough in a lot of scenarios. There's also much more downtime than in Dominion, and that probably also factors into it - more time to find reasons to blame one another.

The matchmaking times should get lower once you rise in level, but atm, at least on EU West, they're like one or two minutes, minimum. Still gets up to 10 minutes for me sometimes, but only very rarely.
