I hate. That's all.
Well no, my problem with hunters is about playing a no range class, without having much speed. So when I reach them, they are usually evading, evading, hiding, resisting, resisting, running, running and making me crazy.
EDIT: I hate also the way ppl say "Hey they kill lvlers, the hit you from the back, but HEY it's the class!"... Imho it's the player that does the style not the class he plays...
