- 75% of wipes happen because of Ranged DPS(s) do not know about mechanics; i.e stepping on mines, including many 660-670s.
- Clueless about how DPS Works; when a melee is forced to heal because of lack of heals or has to run or the boss is going up (Imp i.e) he loses DPS.
In fact my most smooth runs in HC happen with melee-dominated Raid Groups. I even remember once back in Normal where it was a wipe so I was standing around jumping; waiting for the boss to target me and kill me, and still had trash talk after that. Anyway that is my experience.
