Attempts to indicate which members of your raid will be healed by your next cast of Light of Dawn.
Assumes the Light of Dawn targets a rectangle, 10 yards wide and 30 yards long, with the player situated at the center of one end. Anything in the rectangle is assumed to be within range of Light of Dawn.
In attempting to determine which targets within the rectangle will actually be healed, the possible targets are sorted by health deficit and the top 5, or 6 if glyphed, possibilities are indicated.
I do not have easy access to a Paladin, so I am unsure if this is accurate.
