Never been called a casual, but i have been called a scrub healer for not being able to keep up the heals with a full 2nd half of the dungeon pull on AST with two monks as the DPS. (Copperbell HM, pull included the slimes at the end).

In short: i ran out of MP because AST doesnt have anything like divine seal or a quicker MP refresher like Aetherflow and energy drain. And yes i did draw ewer and used it on myself and bole on tank since it was on spread. I was low on mp before pull.
