with 1h i would specialise axe cuz of blooding perk.
ok i tell you my experience: 2 h svck at dragon fight cuz u die so fast, otherwise it works greaat.
pure mage with destruction and restoration: i heard destruction dont scale up enaugh and svcks in later game.
1h with shield: looks boring and too casual for me

but i think it will work great for everything.
assasin: no clue how u could kill a dragon -.-
marksman: could work good if you combine it with 2h?
battlemage (1h and destro): not enaugh defense and weak cuz of spreading points to health magicka and stamina
i think you should prefer heavy if you are a meele fighter, exception is light if you are sneaky.
as mage robes of course, battlemage its your choice wich you prefer...
thats some impressions of my thoughs so far, of course u can experience it in other ways.
