The only thing that's making PVP really not enjoyable for me is warping. Other than that I really like it.
For some strange reason it seems to favor people with crap latency (I got steady 60-80ms) - you see one person to get stuck for few seconds, and suddenly plop, he teleports 30 meters away. Same when you see someone drop from a cliff, you follow him and he suddenly reappears on top of the cliff. The readjusting position after a stun is just icing on the cake that makes classes with positional requirements really fun to play.
