Tashas is Disappointing in a way i don't see people talking about

yes but its part of an optional rule and only helps one acid base character.

It's a rule in the new book that addresses your concern. I can play a sorcerer as any element and change the element with sorcery points to fill in the gaps.

I don't put too much stake on it being optional. Feats are optional and I've yet to see a game run without them.
