My concern is for the state of the wizard. The Vancian system is the weakest of the bunch, leaving the wizard, who already has the worst hit points/armor/weapon options with the worst spell system as well. Basically, the wizard gives up a whole hell of a lot for his spell casting. The only thing that can make that work is if the wizards spells are simply so darn good they provide enough of an offset, which would require pretty potent stuff indeed.
So to me, you cant just look at the "spell system" in isolation, it has to be counter-balanced against the spells it supports.
