I commend the healer when he/she saves a run from a badly geared tank trying to pull like an overgeared god.
I commend the tank when he/she pulls to the limits of what their gear allows and doesn't let a bunch of mobs go and introduce the healer to the floor. And has the situational awareness not to pop sprint and run halfway to Garlemald pulling everything in sight before healer has cast Protect.
I commend DPS when they don't run around like headless chickens and get hit by every circle of death or run ahead ninja pulling more mobs when an obviously new tank is in the group.
If everyone did their jobs well then it's either random, or whoever has the cutest glam/fluffiest tail.
