Well since recently kabam stated that the healing Black Widow CV and Morningstar they get from dealing 0 damage is a bug then flow in AW on path 9 on aegis nodes shouldn't trigger since it can't deal critical damage because of the indestructable charges but i didn't see this being mentioned anywhere.
if there were any doubts about my statement here is a video proof from Swedeah L(on the start of the video you can see it happen):
