I really like it to add some stakes to battles and combined with the houses of Calradia mod that adds AI marriage it's not making my world less populated since the AI marries and get new children to strenghten their clans.
I think the feature just needs some more work still (which doesnt?) Like maybe reducing a little the death chance or making it a bit less RNG with traits, level, age, armor etc counting to death chance.
Also the chance (even if greatly reduced) of death in AI x AI fights because now they only die in battle if you are part of it making the player a deathbringer or something like that lol
