...when Empire powers/Healer class was theorized and implemented, I believe they were envisoned with 80-100 players to be on.

As in, it used to be common for my last healer (circa 2008) to have to defend against 4-5 people at once, solo. Being in Empire, moreso as a High Priest, it was doable.

Now, defending against 1-2 players, it's somewhat overkill. Interesting to try and do as Jhyrb say and think of a compromise.

Maybe since Healers have in their code "healing effectiveness" (evil healers don't heal as much as goodie healers without dark pact), you could find a way to shoehorn "mob healing" rates. As in, if random NPC you only get 5% effectiveness (so 10 hp on a rejuvenate...not even worth it), Cabal guardian/mob 20% (so 40 hp on a rejuvenate...MAYBE WORTH IT).
