I agree with the op in several of the mentioned points in his post.
The same problem happened with WARhammer Online, and the reason why the same is happening here is that they came here to implement swtor too.
Gives you a kick when blowing up to pieces the imp scum doesnt it?
See, you are not only blowing up a toon.. youre blowing up a concept, a belief, a philosophy, a overpowered design character to make you believe that evil is good and strong and powerful, while in fact its exactly the oposite.
When you blow up any sith in pvp you are showing that.. even if they keep favoring the dark side, light, justice and good will wil always be there to guide you through the shadow valleys of everydays life.
So.. and to resume.. let them favor the Sith Empire faction as much as they want to.. cos the more they favor it, the more we republic have pleasure blowing them apart in pieces through the warzones.
Lock and load.
