While I understand an evil healer would be less inclined to care about whose money they are taking it is kind of annoying that so many key goodie healers flat out refuse to serve evils yet no evil healers return the favor.

I think making one or two evil healers in key locations not as goodie friendly might even the playing field. Maybe they don't turn them down but perhaps take their money and do nothing, charge a lot more for the same service, or perhaps just use weaker communes.
