If you don't like playing Huttball. Play Republic. Problem solved.
Yes, it's your money. Yes, you can play whatever faction you choose.
However, EVERYONE was and is very well aware of the faction balance issue at hand.
I played Imperial from server up until server down in SWG. I played Imperial through several builds of beta. When the game dropped I played a BH until level 40. Got tired of Huttball, sucked it up, and created a Counselor.
If you want good PvP, go to the PvP faction - Republic.
Or you know, you can be dark and edgy and a complete and total Imperial hipster.
