Tanks:
Chain pull really well or just pull everything without losing aggro on the first flare. I hate wasting my stacks
Scholar:
Cleric stance entire dungeon
White Mage: you better be holying a lot for taking away my piety

I always queue exp roulette with the same person as we work on the daily alexandrite so never have to never have to worry about dps, just want to be in and out fast
