I just started the game, but I picked upbsome HRM and I'm quiet excited to use them - I think they synergise well with Mccabe and Master queeg and Luna
The predominant trick that I can see is a potential lightsaber and 6attacks (reactive/black flash) - This is obviously extremely resource heavy but, you can do some serious damage, its an option.
I also like their high defense, have Luna give them defensive and they can take up some pretty aggressive positions - no?
What I see being hard to use is their focus ability - I really dont see a good time to use it.
Also, like people have said, they go down easily so you kind of have to target activated models, which can be tough
As far as their damage output goes, its solid, so long as the burninf stays on right?
They can get a maximum of two burning stacks per attack, correct?
