A Mage should rarely take damage. The point is to use your head and unusual abilities to arrange death for your enemies. I will sometimes put on my Flawless Dragon Scale somewhat enchanted armor, then go bash some stuff with my soul collector mace, but usually I wear the Arch Mage stuff and enough rings, amulets etc to buff my major talents to a somewhat OP level.
Level 40 Destruction/Conjuror just did two Dragons at once ... no problem. You need to not get in front of them with no armor, kinda quick death, but two Flame Atronachs distract em' just fine. I have much tougher pets but the hot girls do Dragons really well and you can see where he is by watching them pelt him with fire. I only get hurt when I act brave, I try not to.
