So a skeleton shoots you with an arrow. You take damage and it does as well and it makes sense to degrade twice because of one arrow? Just because thorns is there shouldn't change the degrading, If it should, then enchantments in GENERAL should degrade all armor at double speed because protection doesn't drop double just because it absorbs the brunt of attacks sometimes. Nor does fire protection or blast protection or projectile protection. Just because the enchantment is functioning isn't a reason to say that, otherwise it needs to act like that for all enchantments. Thus, why i pointed it out as a bug.
