Is Restoration superior to all the magic schools? I mean with Restoration you can increase your lifespan, heal wounds, disease, and poison.

Make yourself Stronger, Faster, Tougher, and even Luckier with Fortify spells, you can make wards to protect yourself from spells, and even dragon shouts, you can resist the elements Fire, Frost, Shock, and be able to kick the crap out of Undead fairly easily.
