[2019] Aces and eights super broken?

So I got a decent Aces and Eights builds, does good damage and buffs my team, when it works. I know it should work for the whole raid, but it only works on your subgroup.
On top of all that it randomly stops working. Worked on Boomer, worked on the Wheasel fight, Didn't work on Lucy and Buddy. Worked at the start of razorback fight and 1 minute later it stopped working. I had to get downed for it to start working again... anyone else had this issue? It's really, really annoying.
