Can anyone help me find a decent MOD that makes it more fair, regarding AI Leaders returning the Wounded?

I notice that in my Normal Difficulty games (on Mortal Empires); that whenever I (kill)Wound an enemy Leader in battle. That leader seems to return to the map 'right away'.
Like; I am not even sure if two turns go by... before I see the same full strength leader return to the map and be hired into a full stack army again!!

It is unfair. Because when MY Leaders get wounded. They have to wait several turns, at least; before even being allowed to re-enter the map and hire system.

I seek for a MOD that will increase the amount of turns before an AI leader can "come back" to play.
