isn't destruction magic supposed to suck? any more suggestions?
It's not very good one handed that's for sure. I enjoyed it on my pure mage. Try a spellsword type that doesn't use destruction, I did this and it was a blast!
Start the fight with a summon or two, then switch to a heal spell, or paralyze your enemies with alteration, all while wielding a sword in your other hand. The only spells I occasionally dual wielded were illusion spells since u need to to affect higher level mobs.
