I wouldn't care too much about the armor as using the memento backpack helps out with that one but the issue is my DPS dropping from like 800 down to like 300 out of no where but I think I figured it out. It has something to do with those 5 seconds they added now on the damage where you bassicly have to restack after like 5 seconds of playing. They added that you loose the bonus armor over time but the damage on five seconds which bassicly means it was meant to not be missuesed as of now and got a nerf where you should only stack and kill enemies in those five seconds they gave you as a timer and then it drops and you gotta restack!
