Pure Healer could be a bit more interesting...

[Ceasaria]

The new Asylum and Plenary Indulgence would be cool (but I would prefer it's new spells, not rework).

Asylum would be nice and balance (compared to Living Dead) if at least :
Recast time => 6 min
Duration =< 10 sec
Aditionnal Effect : Cost MP = 50% or even more

Reason : it's better than LB 3 Tank (even if Asylum could not work against some big attack).

Bathed in Blinding Divine Light enemy attacks on party members are now 50% more likely to miss.

It's not very interesting.
You can't really plan who is gonna take damages or not.
Plus, I already hear the WHM complaints : "No more RNG !"
