I was trying to do crotas end on hard for my first time. We got crota down to low health. One more down we would have killed him but he started replenishing his shield at a super fast rate. We had the entire team shooting ghorns with wolf pack rounds. He got killed by the over souls after a couple of seconds. This happened 3 times during the time my team was trying to beat him. This is total bs. Bungie please fix. Please fix all of these annoying glitches that prevent players from completing your raid.
