Wrend barbarian no damage

I was on this morning cleared gr90 with no issues logged back in this afternoon and even while in full COE window with 3010k dps monsters in a normal t16 took 0 damage. Reset game and console same results had it happen on justice monk and god DH last night.

you’re saying your monk, god DH and WW Rend Barbarian don’t do any damage on t16, but easy clear GR 90?

My first instinct if check your build/gear/set bonuses, but if it’s happened with three classes, I got nothing.
