This was a good read. After participating in a few Hami raids, I found my unresistable MaxHP buff (Frostwork) still gives the same HP buff to the main tank. And Incandescence Destiny is still giving that 50% heal resistance. Even with those two things being true, I was surprised at the impact of the heal resistance on the armored ATs when they were hit by the attacks during the raid. This might be a case of something needing tested but there were enough players to do so on beta, so it's being live tested. Good feedback that I think will help the dev team understand the impact of the change.
