He claimed we were the "worst dps this expac" despite, you know, not wiping, nobody even died, nothing at all went wrong except one boss managed to pull out a gimmick one time. Had we managed to avoid that the dungeon would have taken maybe 90 seconds less time.

He also didn't understand mages. Not to sperg out but the short version is: Mages stand still for most of their spells, the boss has an ability that forces you to move or take significant damage. So I can either stand still and take damage (which provoked yelling from the healer) or I can move around and do almost no damage (which provoked yelling from the healer).

So in short avoid Mingzhu from Area 52.
