It was fun, an ha Breton with 1h, destro, and resto.
About level 30 I hated him. Spent too much time smithing my armor and only had destro up to 65 with not enough mana.
So I started over a Breton spelksword.
Got destro and 1h up to 25 before I left Helen.
Killed some thalmor first chance I got and started wearing elven.
I decide to concentrate on destro only and carried a mace just for back up. Along the way I wore my novice hood and destro robes, so I only have boots and gloves armor wise. For a while I lowered my level to novice because I was getting my ass handed to me to much and I wanted to raise destro faster. Joined the TG so I could steal some stuff to pay for my destro training addiction.

Now I am level 16, just got the oghma, bought the riften house and still haven't progressed much in COW or TG.
Once I got the impact perk destro was fun!
People [censored] about it but hey, I am standing there naked with basic health and I am being attacked by something with big ass teeth, claws or a weapon the size of a tree trunk. If I want to burn up my mana by glazing your eyes for a few seconds so. Can run away or regroup. Then so be it. That is what a destruction Mage is all about. Yes I can see it being abused, but if that is my only defense. (no armor, wards, flesh spells or summoned sponges) then that is fine.
I realize now that I am playing a pretty much pure destro Mage without intending too sure some of my other schools are creeping up, like LP, conjuration ( from soul trap) etc, but it is FUN!
My plan was too eventually craft up my armor and illusion, but for now I am at 66 destro and I need to get some destro reduction gear.
I am spoiled by the speed I can move at with no armor and lighting bolts are FAST. Much faster then bows. Killing deer is so easy i can feed the imperial army with my venison and cloth all the forsworn out there with my leather

Well, that's slighty exaggarated, about as much as one unblocked hit
