[D&D] When you snag the Anime 5E pdf not expecting much then discover that it has a super customizable point-based leveling system that addresses balance issues between martials and casters and also has comprehensive size category rules that the actual system ignored entirely.

I'm still reading but this, honestly, seems pretty well done.

It's a bit out of date and I'm wondering how this system would interact with newer subclasses and races but I think I can tweak it well enough. It's also got its own set of both to pick from.
