Your statement IMO supports nerfing melee damage over buffing up destruction damage. Melee damage grows to much in relation to level in my view. I am not stating this as fact just as personal opinion.
Somewhat, yes, but I still do want destruction scaling (though not on the order of melee/archery with both enchanting and smithing) because it would fix a bunch of destruction "fun" issues. I remember having a blast when I first got my runes spells because I could strategically place them before a fight, or when I got my walls spells for the same reason. I think flames would have been fun to use if I ever got caught in a melee situation. But, as things stand, I am reduced to basically incinerate/thunderbolt spam at my level because all of those spells are now obsolete, and because incinerate/thunderbolt still hit for so little (it takes me 15+ hits to kill a draugr deathlord, and at my level the game considers them not bosses but an average mob to throw at me) even they (incinerate/thunderbolt) aren't fun.
Spell scaling would fix the issue of low damage while giving us access to ALL of our spells again, instead of forcing us to use just one spell over and over. I really don't see how anyone could think this is a bad thing. Combined with other trees and perks, destruction mages would be enjoyable to play again.
