If they can't balance spellmaking, they should get rid of it. I can hardly see getting rid of it takes away all this freedom.
If they can't balance spears, get rid of it.
If they can't balance levitate, get rid of it.
If they can't balance crossbows, get rid of them.
If they can't balance thrown weapons, get rid of it.
If they can't balance mounted combat, don't do it.
If they can't balance enchanting, so get rid of armor slots and clothing layers
If they can't balance birth signs, get rid of them.
If they can't balance the economy, do away with placed loot or give merchants set gold levels
If they can't balance thieving, make it so you can't sell stolen items, or 90% of the time there's nothing worth stealing.

I've said it before, I'll say it again. Don't let a puritanical, ideological drive for "balance" deprive the player of options, freedom, and customization.
