The point is, the ability is hindered useless when healers and dps and tanks are doing their jobs correctly. It needs to be changed so it's not situational and is useful for people to drop in a raid. Again, I'm not talking about dealing with players who don't know how to maximize themselves, I'm talking about in world first progression situations where the ability is completely useless and that's the primary issue with the ability, and not the fact that it's useful in some situations because your raid isn't optimal.
Again, don't bring up the BS of bad dps/healers because that's not what I'm talking about and is completely irrelevant to the conversation. The current spell is useless to the majority of end game progression raiders and needs to be changed accordingly.
