Yes, I came to this game after seeing that the pvp wasnt something to laugh at, and how it actually looked fun instead of a grind to get the gear to get to wear it gets fun(not saying that there are other games that are a grind...)
I lag some in huttball & voidstar, though its generally just a half a sec- a sec ability delay there, which reduces my performance and makes it less enjoyable, but is still doable. Alderaan civil war is just fine, until i enter combat, then it doesnt matter what i do the rest of the match, the lag is untolerable, much worse than even korriban on the first day of a beta weekend.
I don't know if this helps, but they asked us to post this on another thread about lag in general, so heres my dxdiag in spoiler(comp name removed)
