I was thinking to level 3x warlocks 1x priest and 1x mage (Maybe ones I hit 60 on my Shamans)
I picked up 5x elemental shamans, level 12 1/2 the Q times after work are 2.5 hours.

I can't really level up faster. Shamans are pretty great so far, 1 shot the mobs starting with LTG bolt/EarthShock. I picked up all the professions, Skin, Herb, Mine. I enjoy the Game so far!
