or, like the most of us, come impside and have better pvp.
I tend to disagree. You aren't getting better
PvP. You are playing with the same players after all, they just happen to be on the other side. You are getting easier
PvP and more wins, and perhaps that is what better means to you, but if balanced, competitive PvP is what you're after, it can be argued that this kind of behavior is just part of the problem rather than the solution. It's understandable, I don't like losing my way through my daily either. Still, I find it unfortunate to wholly give up playing on a faction entirely. The typical responses you listed after giving advice are not unique to republic players, you'll get that on either side. You probably just find yourself seeing it more often on the republic side because there are fewer premades, and hence, more losses and frustration.
