(Bug) Berserker Class not taking damage? (PS4)

Play as Berserker some games I take no gun dame from Fireteams. Some games I show no blood, or blood trails.

Playing as fireteam I saw these same bugs happen. Is this due to the update? 🤔

I never noticed that as fireteam player though - Seems Berserkers are actually the easiest ones to kill for me, because they are really slow.

I thought it was the extra health. I never considered it could be a damage glitch.
