Just reading the forums to see if anyone is as disgusted with the priest talent tree's at the moment as I am, and I came across some comments regarding holy having a different signature ability, and I had an idea for a new ability:
Ability name: Prayer of the Holy Pilgrim
Description: Instant cast spell which creates a holy aura around the Priest for 10seconds. The aura will heal all players within 20yds for x amount every second. The amount healed is increased the closer the Priest is to a player. No other spells can be cast during this time.
I picked the name because the idea is to cast it and move around healing people as you go (as if on a pilgrimage, yagetit?). Would be handy for movement fights, or as an emergency CD like Prayer of Healing. I believe the mechanics for such an ability are already in place, ie Loken has an aura that does damage the further away you are, just reverse that and turn it into healing.
