I've noticed that in battles the unit I send first into battle usually get casualties healed at the rate 25%, whilst later sent units don't get any or very few.

This might be important if you say charge with your feudal knights first, rather than say use a sacrifice charge of pilgrims.

Thats my impression anyway, anyone have a better thought than this?

I havn't been able to track other posts on this topic.

BTW are there any doctors or healer traits to further reduce casualties.?
