There is no cross-class Regen.
I think a lot of you are doom-saying a little bit too much before even getting to know more about the new core mechanics of WHM. I'd wait to hear more about the job's flower-based stuff before jumping to conclusions. The fact that Protect, Divine Seal, Esuna and Cleric are now in role skills means that either WHM can get new skills that come with utility or mitigation (or both), or that the other healers are losing skills too, since they want to avoid hotbar cluttering. Particularly in the case of Divine Seal, since it is a
job action, this means WHM DEFINITELY is gonna get something to replace it.
Stone IV was an obvious addition since all healers need an updated potency nuke to keep up with DPS (which will replace Stone I/II/III in our hotbars, as well as Ruin and Broil, yay!) so I don't see why anyone would complain there...
I know their comments weren't exactly uplifting, but don't go so far as to bury WHM just yet, have a little faith in your main job

.
Btw, the fairy tether makes me think Scholar's healing output through Eos is getting a rather heavy handed nerf, so there's that at least? lmao. The fact that they decided to showcase AST's cards with Arrow instead of Balance makes me suspect Balance might be reworked somehow... but we'll see.
