Honestly, while some racial rebalancing would be nice, I don't think that unbalanced racials are actually that big of a deal. I played as a gnome because I wanted to be a funky little magic dude and didn't really care about the racials. I mean, they outright don't matter, because you absolutely do not need to optimize yourself at all even to beat this game at the current highest difficulty. I'd much rather see some tweaks of the subclasses (I know wizard has the most, but good lord, the subclasses on wizard range from 'unbelievably busted OP, what the hell were they thinking' (Diviner, portent dice were already considered amazing why did you give Diviners 3X THE AMOUNT PER DAY GOOD GOD), to 'More OP than tabletop but cool implementation' (Abjuration) to 'this has to be a placeholder while they figure out what the actual abiltiies will be' (transmutation)
