Dno maybe your doing something wrong, 4-4.5k mauls on procc (wich is the only time you should maul) is also a very commen occurence for me.
I agree here, 5-6k crits on assasinate is something I have yet to see, again 3.5 - 4.5k depending on class/lvl etc. of oppenent.
Dno I find our dmg to be fine, my only problem is that I find scoun/ops opner burst to be to high, outside that its fine, as for BH/commando my only problem with them is that its a 1 button class (graveround/tracer missile), these can be interrupted or cloaked, none the less it still feels like to much of a 1 button class from my pov.
But as I said I feel that our dmg when geared are where it should be.
I think that ppl sometimes seem to approach this class in a way I dont agree with, wich to seems to be the reason why they got issues with it.
