After healing through Doma Castle, I'm still not feeling the MP problems too much, but I did notice if the tank doesn't pop cooldowns, we are having to work so much harder to keep them alive than we did back in Heavensward due to the fairy's Embrace not being strong enough to help with the healing as much as it once did. If they pop cooldowns, it's about the same as it was then. That of course requires the tank to actually be willing to make the job easier on the healer.
