How about the option to always choose your highest applicable ability in a given situation? Still on my first playthrough (game was super unstable until the hotfixes started rolling in), and I figured I'd play barbarian/warlock on a lark, given I know what paladin/lock does in 5e and it looked more OP in BG3. Building lower STR and higher CHA for blade pact doesn't work because Rage causes a lower STR score to override a higher CHA score. If you have base 12 STR and base 20 CHA and Rage, you're going backwards with no agency. Given how other class combos function, I don't think letting your better score dictate what happens is too big a deal. Not even asking for the extra damage here, just the ability to use the better stat.
