to be honest, no I'm not playing him like that at all... I've playing usually with a one handed weapon and then a destruction spell (usually 'flame')
Sometimes I use a shield, sometimes I use a 2 handed weapon but i'm a bit slow with that.
2 handed = 28
1 handed = 44
Archery = 20
light armour - 19
sneak - 25
lockpicking 30
pickpocket 21
speech 41 (i have an item that adds 15 to it)
alchemy 31
illusion 15
conjuration 18
destruction 27
restoration 18
alteration 15
enchanting 25
smithing 30
heavy armour 32
Of course, I have not accessed the base perk for all of these
Ya if your going to use magic offensive your going to have to pump up your destruction skill. You need to have at least one good offensive perk. Looks like your one-handed is really good but that does not go so well with light armor and no sneak. Use sneak + light armor + one handed or use heavy armor + one handed. You can also mix that up with one-handed + light armor + destruction (fire). This way you kill your enemies fast before they kill you. They way I look at it is you have 4 offensive options and 2 defensive options for this type.
Defensive:
1. heavy armor, one-handed, restoration or some other defensive school of magic in off-hand
2. heavy armor, shield in off hand
Offensive
1. sneak, light armor, dual wield
2. sneak, light armor, one-handed, destruction off-hand
3. heavy armor, dual wield
4. heavy armor, one-handed, destruction off-hand
Note on heavy armor and magic, I am not aware of any direct negative effects using heavy armor and magic other than you are much slower in heavy armor.
