Basically yes. From how Yoshi-P explained their reasoning for the EW healer changes, or lack thereof, ANY healer that isn't a GCD heal spamming curebot, who has 90% of their attention fixated on watching Netflix, should just play Sage...or as they would probably call them: "the elite healers"
It's not just PLD. Warrior gets even more selfheal than it currently has (and more consistent healing through Nascent Flash/Bloodwhetting in bossfights), another 1000 potency on Equilibrium in the form of a regen, a 400 potency heal on Shake it Off, 20% mitigation on their Nascent Flash replacement.
GnB gets 2 charges of their HoT (Aurora) and ~28% mitigation for 4 seconds every 25 seconds with an added 800-850 potency heal should they drop below 50% (Heart of Corundum).
DrK is pretty much the only tank that got the absolute shortest end of the stick, all other tanks either got a ridiculous amount of extra mitigation, selfheal or both.
