Sounds convoluted but ambitious. If it does happen, I'll surely have a chance at it.
It is somewhat but I feel it could be a pretty decent twist on the YT AI watch series idea that you saw a few years back. Currently just trying to implement said nerfing system in ZSS since that would defiantly break the staleness that they bring with the more top tier characters slowly getting nerfed over time with their attack and maybe defense if need be when they rack up those Ws. It's been uh... "fun" so far trying to implement that.
EDIT: Pretty much have the nerfing system down pat, just need to get the buffing system along with the saving and loading functions to load properly
