Reading through the 3.0 players handbook and there were some small changes that may have been easily missed between it and 3.5, like gnomes going from a favoured class of illusionist to bard, which also explains whey the iconic bard became a gnome in 3.5. I'd also forgotten about favoured classes, I think served a similar purpose to class restrictions in 2e, but instead incentivised picking a specific class instead of restricting them.
I've also been so used to bull's strength type spells from the pathfinder crpgs that I'd forgotten that you had to roll for the ability boost instead of getting a flat +4. Pretty sure the flat bonus was a 3.5 thing.
I also sort of like the specialist wizard a little better though I guess there isnt functionally too much difference between 3.0 and 3.5, but restricting your choices of opposing schools (while providing a menu of options) is a bit more interesting to me.
