Sith is extremely overpopulated. My guild switched to Republic exactly for that reason. And I have to say that the Republic side sucks. The story is boring and poorly written and in PvP the players are the absolute worst. However, the Warzone's queue times are non-existent and I rarely get stuck playing Huttball. But to solve your problem original poster. Just log off when you get pushed into Huttball. It'll take you right back to the character selection screen. Then log back on again, wait a minute or two, then re-queue for a Warzone. Just keep the queue while you're questing.
