enemies healing while in combat

[Dexterous 0]

One thing that is killing the enjoyment of the game for my buddies is the healing that enemies do during a battle. It seems like wolves, crocodiles, bears, etc all heal massive amounts while fighting you and it just takes away all enjoyment out of the game. hell, even birds get massive health regen during battle. I understand the army of the dead resetting if someone is trying to cheese them by not being attackable but the regular wildlife shouldn't be healing while you're fighting them in melee range.

Has anyone figured out a setting that would stop healing during combat? Or just reduce enemy healing by 90 percent? Any tips would be appreciated!
