1) I dont feel its a single player game, since i always group with my friend, but maybe we feel differently because of that.
2) I agree with all these bugs, would be nice to have fixed.
3) Completely agree!
4) Agree. Also healing (im a healer!) is quite underpowered in PvP. I can hardly outheal 1 dps, no chance vs. 2 (and its normally 2vs2 or something like that, guess who they focus fire on -> the healer). So 2 dps vs 1 dps+1healer is sure win for the dps'ers.
