When you first enter the game the reason you can't cast anything is because you need to rest straight away as your spells are all erased from memory. In my personal opinion a speacialist mage is better than a sorcerer, I feel to restricted in the variety of spells I can cast with the sorcerer even though I can cast the same spell many times. Mages get there spells faster to.
