I could go for at least one more WHM attack skill, maybe one that give the WHM a dmg buff or the mob a resistance debuff. Perhaps via Stone II to keep it viable, or if completely new, I'd like it to have a dia animation.

I think WHM could also stand to get some form of proactive AoE mitigation as it's the only healer who can't mitigate magic raidwide dmg. Stoneskin II buff maybe so it could be used in combat, or even a new skill that just lowers magic dmg of a mob for a duration.
