Long queue times, unbalanced games?

Hey, been trying to get back into Dota 2 lately.

Are there peak hours in which I have to queue for All Pick (EUW)? I've queued several times and it always went beyond 4-5 minutes, after which I stopped and queued Turbo instead.

Also, the Turbo games are usually quite unbalanced. It's mostly just stomps, because there's one or two very good players on a team and not the other one (I'm not one of the good ones). It really sucks the fun out of the game when you know the next 20-30 minutes will be sitting around, waiting for the enemy team to finish.
