I would like to preface this by saying that I haven't done any Ultimate fights and I only have moderate Savage experionce, so take my claims with a massive bag of salt, however: I think the state of healers is inextricably linked to the state of tanks, the two minute meta and general fight design.

Firstly, the state of tanks: Everyone knows tanks have been getting more and more sustain to the point that you can basically ignore them 90% of the time unless your tank is DRK, in which case they need some healing very occasionally. They eat a tank buster? No problem, they can just heal themselves up, the healer doesn't even have to slap a regen on them anymore. The tanks can also heal each other to such a degree that healers barely have to touch them at all unless something is going extremely wrong.

The two minute meta means that you can't fix healers by just giving them more buffs or utility. Everything *must* align perfectly with burst windows and party buffs. Frankly, the entire concept needs to go.

And lastly, I think the current fight design is hurting healers a lot. Big AoE damage is, outside of specific exceptions, scripted in a way that one of the healers can just throw out an OGCD heal and forget about it, unless we are in the early weeks of the tier and everyone is rocking garbage gear. Everything is designed around the entire party pumping out as much damage as possible, so healers are actively discouraged from ever casting a GCD heal unless something is going horribly wrong. We keep getting all these new shiny healing tools but barely any incentives to ever use them.
