My dom totally rocks. I always team with a same lvl mm. Her pets do all the damage and I keep them from running off by keeping the enemies where they are. Also they each do increased damage because we both have assault and tactics. They are really powerful in groups, but I can solo groups of 6-10 whites/yellows with lieutenants if I have my fly trap and carrion creepers out. I hit them with my seeds of confusion, then roots, carrion creepers, drain psyche, and psionic shock wave. My fly trap goes to town and carrion creepers does more damage then I would have thought, plus it takes aggro and can't be killed. I strangler whoever didn't get hit by seeds and if they all did then I'm free to take out the boss with my snipe. If I get my spirit tree down and my drain psyche hits all I have to worry about is getting held or slept. If I have domination I don't even have to break a sweat. People underestimate the value of spirit tree, but in conjuntion with increased defence due to maneuvers or hover it works really well. Happy Hunting!
