I don't know about crafter's healing, but Almogavar being free in Grogs is a typo that's been fixed in the errata - it really is a Minor Virtue. Personally, I think it's a weakish Minor Virtue, and I would have fixed it by e.g. adding some xp in Martial Abilities. But if what it provides is left unchanged, it's probably more fairly priced as a Minor Virtue than as a Free one. See also here for a discussion of how it balances out compared to other Social Status Virtues; note that the post was made before the errata, so it's still listed as a(n excessively strong) Free Virtue.
