I didn't have the bug fix and I'm using xp. Cheers guys.
Indeed - level caps don't "balance" the game, they just ensure that the game is unbalanced both at low levels (in favor of demihumans), and at high levels (against them). And I don't think most tabletop campaigns ever got up to a level where level caps mattered, so it was pointless anyway.
I think my 18+, 9/9, 6/6/6 idea would work quite well if it can be done. If not I'll just get rid of the limits. I'd like to add an elf ranger, elf and half-elf multi classes that replace fighter with ranger, dwarf cleric, cleric/fighter, dwarf and half-elf cleric/thief, cleric/fighter/thief and gnome cleric, mage, cleric/mage, cleric/fighter, cleric/fighter/mage, mage/thief, cleric/thief, cleric/fighter/thief and maybe even cleric/fighter/mage/thief for half-elves and gnomes.
