Also Alchemy will give you a better damage output, something restoration cannot do. Fortify One Handed potion will increase your damage.
Also, alchemy will give you potions that will make you better at other skills, depending on the situation. Waterbreathing, Cure Poison, Cure Disease, and even Invisibility are some potions you should carry around.
I'd rather put Fortify Block on the shield instead of taking Shield Wall 3/5. For me it is more "cost efficient".
