You clearly don't understand how good cascade point is.
Pair cascade point malfeasance with lucky pants and you have one of the best burst damage weapons in the game.
Nah, man even on other classes it would be worthwhile.
You're rarely doing DPS with just malfeasance, so imagine emptying your auto loading linear, whipping Malf out and blowing your whole mag in less than half the time it usually takes. Then reload the hand cannon and swap back to your LFR to repeat.
