If I'm understanding the first part of your suggestion correctly, you want to lock the extra SP we get from Class Point Traits (such as Spirit Caller for Summoners, as an example) behind Legend Extension and Legend Inks. It's a no from me, especially with the added stipulations of nixing the traits altogether to make way for this proposal. It just doesn't make much sense; most classes also weren't reworked to 3/3, by the way. And just because human racials exist doesn't mean other races benefit from it like humans do. That was in fact added to bring humans up to height with other races who more benefit from their racials.

Legend Extension already gatekeeps some stuff that it shouldn't, and grinding is usually boring and a slog. The traits are fine as is in my book. The only benefit I see is having extra trait points to use, but most people have an overabundance of TP anyway.
