How does SE plan to restore White Mage's identity as a healer?

[Docteur_Fluttershy]

again with that? really?
Benediction isnt a oh-shit button, it has a long animation sequence, and if you use it as an oh-shit button, you'll just heal yourself.
tetra is 700 potency every minute, sch has lustrate up to 6 times per minute for 600 potency => 3600 potency.
When you know you need about 3200 potency to fully heal 40k HP, you'll see that the lustrate are way better at that than tetra or benediction, because you can control it, where benediction, if it actualy land, will have a portion of it in overhealing.

and AST instant heal is at 1000 potency when the HP are low, so if you forget about benediction as a oh-shit button, whm is dead last.

For the regen aspect, diurnal AST has the same regen ability as WHM. (medica II + regen + asylum => 50+150+100 is nearly the same regen than collective unconscious + aspected benefic + aspected helios 150+140+40, which make the AST do more regen.)

So in both way, WHM doesnt have the upper hand.
The only real upper hand WHM have is cure III and benediction (not as an oh-shit button).

And dont talk about aspected helios and medica II range, else i'll bring the asylum necessity of staying on the same spot for 24s, while CO gives the regen and you can move out. (moreover, AST can prolongates the regens).

oh, and by the way, sch has indom instead of assize, which heal for higher, has a lower CD, and isnt required to use often cause it doesnt influence a lot in his mp management.
