Merely surviving is extremely powerful against mages already, since they are dependent on doing most of their damage on a single rotation of their abilities. They then spend precious seconds doing nearly nothing, where a carry still may kill the hell out of you.

Also, returning a percentage of a mage's damage back to them would likely instantly kill them after they cast all their abilities, and that'd be...well, kinda stupid.
