Janky bday elite gauntlet boss interactions

[Cocacolastic]

Weapon proc missing even though im literally facing close to the boss and on fully charged attack. Sometimes it takes me 1-2 more charged attacks just to hit the boss, by that time all my gear procs are already done.

Weapon proc/dot getting cancelled??
I fully proced bs shield and suddenly the boss stopped taking dot/blood blast dmg? Its like they get on a cutscene and all dmg/debuff gets cleared. This happens so much on korgar and lich which is so annoying..

These interactions can add 60-90 seconds more time on my runs just because they waste my proc and i have to wait for the cooldown.

Are these intended? Bcs if so its such a pain in the arse.

I haven't looked, but they probably purge debuffs on phase changes.
