Problem with Huttball? Go Republic. Classes are pretty much mirrors aside for graphical differences. You can pretend to be a Sith Inquisitor ,if you must, as you shoot rocks out of your fingers and throw giants rocks at people's heads.
If choosing warzones were implemented the tears from the Sith would certainly drown the few Republicans there are as they wait in hour long queues. But then again I suppose pain and agony is part of the Sith way of life...
