Go back to early cataclysm levels of healing / damage
Maybe not. I don't know what to do about it exactly, I am not a game developer. But as things are right now, the game leans so heavily towards everything just being about DPS, and the role of healing (And from what I've seen, the role of tank) just isn't being treated as their respective roles anymore. Everything is about how much damage everyone can do, and I don't think it's fair for the healers that want to have their healing challenged, and tanks that wants their tankiness challenged.
