Agree. I was 100% sold on a mixed melee team for pvp and pve until I saw the new 31 point talent trees.

Losses:
Cleanse.
Divine Shield/Divine Sacrifice rotations.

Gains:
Insta cast mid-range heals instead of Flash of Light.
4x Hammer of Wrath every GCD while Avenging Wrath is active.

It's going to be insane. Insane I say.
