One clarification, though: minor healing is a universal spell, but it's still a spell, which means it's a skill in the mystic arts category. That means the fighter, thief, monk, or any of the "villager" professions from Folkways consider it to be a nonprofessional skill, which means it costs 4 points per rank. Still viable, just more expensive. Also, there's a number of cantrips from College of Magic that can help (heal bruise, heal cut, relieve pain, etc.) - if all you've got are minor cuts and scrapes, and they only cost 1 MP each to cast.
