It would be really helpful if all kinds small injuries (under 5 or so) would heal slowly. Say 1 point a week. I have multiple deep cuts that are 2 or 3 damage and it is very costly at the point I'm at to bandage very small wounds. I do bandage the 9+ ASAP and recently done the 5-8 ones.
Another option is to allow bandages to be divided among multiple injuries when they are small. A poultice can be used on a 9 deep cut, let us split it in 3 to work on 3 small ones.
