Glad you're being honest.
1 point though.
My healing wont be a factor in enrage timers. All i do is keep people up.
Healer DPS is a factor in the strat my guild uses to clear EC NiM due to the enrage timers. I'm sure with more DG gear it will be less of a factor but not right now.
Given how relatively simple it is to get full campaign / black hole gear, I'd suggest you put in your 2 - 3 weeks and grind it out. I'm told you can RE war hero mods with a cybertech / artificer for stabilizers, so having them crafted might be a possibility as well.
