I think the worst of AoC when i played was the constant split of players on the same party, to other instances, and, the fact that u can only see them on the minimap on a very short range. Those can be fixed easily i think, but i got so annoyed man...i just gave up. Also the gathering professions and..meh...i dunno, it really didnt grabed much of my attention, only the graphics were outstanding. I think that in some months it will be better overall, but i'll stick to wow for now.
