I would rather poke my eye out then be tortured by the "story" on republic side. It about killed me in beta. This is why they have to have cross server warzones.
Won't help if the entire game population is majority empire.
Doubt that'll be the case though.
I expect the imbalance will even out after a bit, but who knows.
And I liked the republic stories, the trooper and smuggler ones best. Only played to lvl 12ish on a trooper during beta, but...it wasn't a terrible story by any means.
Hell, I like ALL the stories.
