This is a priest that's more to healer, but easier solo leveling.
This build makes it easy if you don't have any other DPS char and you want to farm stuff. Just DOT 2-3 mobs (If same level, and eq low), and self heal, with a lil use of Judex for extra damage to multi mobs.
I'm not sure if Sanctuary is too high. Coz Sorc Deluge most of the time enuf to heal, and they are on par at level 3/4 sanc.
What if 4 points of Highness Heal goes to Sacrament? Increasing your overall heal capabilities by 10%. That is if you prefer to use Aspersio with Heal for crit. But I prefer using Aspersio + Highness Heal for the Heal DOT.
64% + 32% = 96% heal to 3 party member. And then 96% heal over 10 sec.
This Priest can go to Pure Support by moving 4 points from the left skill lane to max out Sacrament. Not a big difference. :P Just harder to solo leveling.
