I'm curious to see what the healers are going to get through their 90-100 range...

Healing actions? We have enough gcd and ogcds to the point that anything else is going to be redundant, even charges. Unless they add more frequent healing checks to the encounters specific to Dawntrail onwards.

DPS actions? Could be a route, but since they never gave any indication of adding more complexity to healer's dps kits, I think this is unlikely.

Support actions? We already have too many instances of mitigation rolling around, unless it's some kind of new thing, much like Expedient did with the sprint.

I feel that the healer role is getting (or already got?) to a brick wall where it's very difficult to evolve towards any side.
