Think that's a decent solution, but I still say that by simply making the below change to the Wizards casting and preparing spells is more thematically on point for the wizard and is just enough of a hindrance to keep it from being way OP. Suddenly need to teleport or fly away? If the monsters on on your heels and you don't already have it prepared, it isn't going to help you. Suddenly ambushed by a dozen monsters and don't have fireball? Out of luck. But if you have the time, your spellbook should be open to you.I love it. Yes, this is better.
