Yeah. I'm not sure what the right balance is for how or what spells player's should get.I never really liked that rule. Make stuff available through treasure, trade and purchase, but the new spells of the players choice per level thing is too lenient for me. I'd rather it were random, or nonexistent.
I think narratively, it makes sense that they'd be training to execute some number of spells they want to learn, so I don't think I'd want to take that away entirely.
Maybe it could be tied to the Arcane skill in some way? I think PF2e does it something like this where you have to make a roll to copy something into the spellbook.
