Not mentioned thusfar is Dark Melee. You have shadow maul, whose cone is much larger for Tanks. Then you have Touch of Fear, Soul Drain, and Dark Consumption all PBAOEs. I played for years and never really got into DM, but the change to Touch of Fear is a big help with procs in it. I have a Rad/DM and Bio/DM Im playing a lot right now, and have a Fire/DM sitting on the shelf waiting for playing time.
