I run a SK/Cle/Enc/Wiz/Mag/Bst group right now. Solid dps, utility, mobility, and I never run out of mana. However, I got wrecked in a TBM mission that requires a strong melee dps burn. I have always enjoyed the fire and forget pets but I am starting to wonder if replacing the beast with a zerker would get more sustained and burst dps?
