Evolve WHM to me seems to take the whole concept behind Afflatus GCD healing <-> Blood lily damage refund and extend it to every healing move or so.
It also gets a pvp combo like other jobs behind one button.

Remains to see how it plays because if just to have fun beyond spamming the attack button when nothing is happening means overhealing people that are already full HP so that we can enjoy the full kit, idk, that sounds awkward.

I think I like the idea behind having to stand still to heal and being able to move freely when just filler-ing damage?
