[Another Wanderer]

I'd support giving Witch Doctors the ability to heal diseases like Arco priestesses can heal any affliction. (Everyone who hasn't yet should note that the suggestion was to give Witch Doctors the ability to heal only diseases, not other types of afflictions.) I don't see it shattering the game balance, as it isn't terribly useful against most enemies. Mostly perhaps Dead Ermor if you miscalculate your need for supply items, and C'tis with Miasma theme, I'd think.
