Was thinking about what I would really want if I could design my own skill and why I would want it would be something like:
_______________________________________________________________________________________________________________
Ability-
Indemnity:Restores target for 200 potency while reducing magic damage taken by 5% and applying a heal over time for 12 seconds. Regen potency 70. Cool down of 60 seconds. [Total healing potency of 480.]
_______________________________________________________________________________________________________________
Wraps the base potency of Erase, into a mild Apoc, with a short but powerful HoT. Lets RDM support on the OGCD without being broken and do it frequently enough. Its one skill with a bunch of built in effects, encompassing small support effects like a RDM should be able to have adding up to a difference.
