I honestly think WHM is in a good place right now and compared to Stormblood WHM which we will never go back to, also Aquaveil additional mitigation gained this expansion, Lillybell not to everyone's taste but literally drop it down on the right time with some Aoe + other mechanics going on and it heals all of it whilst you move on to casting glare.
I do agree with one thing though and that's the cooldown change 3 min is a bit too long, although we have patch 6.05 coming up which usually brings class changes along with it.
