I think the problem comes when more than one group tries to do the quest at the same time or joins in the killing. A group I was with killed centaurs for an hour without him spawning, but there were other people in the area. The next day, I joined a group and did counterattack with noone else in the area, and everything worked perfectly. It's just a theory on my part, but it's one that makes sense to me. Blizzard needs to make allowances for when multiple groups are in the area.
