Why doesn't defeating the enemies consider an "end of turn" and trigger the Auto-regen/Auto-refresh/...etc effects?

TL;DR: the title

Hi guys,

I love this game and enjoy a lot of the stuff it offers, but this is one of the few things that is annoying.

I pulled Dark Knight Cecil last week and I found that he become really good once you awakened his abilities which I did. but i discovered something really annoying and made me salty as hell, which was that his healing trait wont trigger if you defeated the enemies and moved to the next encounter.

I know some will say Auto-regen is usually a crappy trait, "I mean who cares about 10-15mp or 120hp when your unit have thousands of hp, right?". But that doesn't change the fact that if they changed it to count "defeating the enemies" as an end of turn that would make the "do something at each turn" abilities more consistent and reliable and would be a nice QoL change to have. and DKC especially relies on his heal so you don't have babysit him or otherwise he is gonna kill himself.

I hope this will reach the dev team, and would like to hear your input on this topic guys.

Thank you for reading
