I can see how the healer was annoyed. Someone who is still their class and not their job usually entails bad use of their skills as well. Like when I encountered a Mrd in Cutter's Cry who was pulling even single target mobs with pure use of Overpower and was not using any def cds. Not to mention they weren't taking advantage of their million possible cross class skills from other classes since ahem * Mrd was their only class that was ever touched. I would've seen how he played first before telling him anything.
