I haven't been inclined to use wards so far... and I'm at level 46. I'm open to try it more. I know wards protect you from harmful magic. But if healing spells recover you from harmful magic, isn't the only difference the school of magic you're advancing? I suppose you could even go the alchemy route and make all kinds of healing potions.
Wards are restoration, just like healing, so you are actually advancing the same school either way.
