rolling Draenae

[Tal]

Here's the information on the healing ability:

Blessing of the Naaru

Activate to heal your target for 50 health over 15 seconds. 1.5 second cast time and 3 minute cooldown. Scales with level. (Given value indicative of a level 1 character. Heals for about 1085 at level 70.)

Sadly it's not an instant cast. Given this info, what classes can make the most use of it? Pallies I think would be out as they have better heal options. Although this one doesn't take mana.

My paladin would kill for a HoT.


Of course it might take awhile for her to kill whatever it is but she'd love to have a HoT spell.:)
