I queue solo a lot and when I get tired of being teamed with bad players I roll in a premade. I don't have a problem pugging against premades, some of them aren't good at all and if they're pro at least the game is over fast.
That being said I think most players that complain about premades aren't really good, I mean first it was gear that was holding them back and now it's premades.
This game doesn't have population to match premades vs premades so I don't expect they will ever remove them from regular WZs.
