I was watching a level 82+ moonkin questing and single non-elite mobs were hitting like a truck and took almost half of her HP each time, and moonkins even have loads of armor. I love doing grind quests with style by pulling 10+ mobs at once with classes that were good in it, like affli lock, shadow priest, retri pala and tank specs ofc. It seems like it's not longer possible after lvl 65, except for maybe tanks with good avoidance?
