Tactiks

I haven't seen Rad/MM in here yet. I run Achilles Heel -res procs in 3 or 4 of my primary ST powers, and in trials I cap out at 1600 damage with cosmic burst, and over 1000 for the other 2 (Xray beam and something else I can't remember the name of). Outside of trials and the obvious buffs, I still can hit 1000 per cosmic burst. Does fire do that kind of damage as well? I haven't played one past lvl 20.

/MM is just icing on the nuclear cake.
