What he means is that when people put up numbers for melee and archery, they always include maxed Smithing and sometimes even Enchanting. So they're comparing one skill - Destruction - against at least two, which is not and should not be balanced, because two skills are obviously better than one.
Right, but that's part of the nerfing of Magic. If melee and archery gets damage boosts from Enchanting, then there should be the same boosts to damage for Destruction too.
Destruction should have one damage boost that is constant effect, but it doesn't... it has to use potions over and over. It is an inconvenience... it feels like harassment to require mages to go to the inventory all the time. Melee and Archery get not one, but two constant effect damage boosts in smithing and enchanting.
And then Enchanting is like having two constant effect bonuses available by itself as you get damage increases to the weapon and you can have rings, necklaces and clothing that boost the damage of weapons.
Where is my ring and clothing that can boost Destruction damage?
My Dagger has both Ice and Flame damage, why can't I have my spell that has both damage types?
Who cares if spells look pretty if you loath using them due to their being ineffectual and monotonous?
Why don't my spells level like weapons?
Why?
The answer to these questions and many more is that Bethesda chose to say "NO" to pretty much everything concerning magic even while it said yes to everything concerning other types of combat users.
basically, players want to be nukers*. Skyrim won't allow you to be a nuker* - hence the non-ending debate -------------------------------------------------------------------------------------------------------------------------------------- *nuker = offensive magic user with the ability to destroy his target in one to three shots I WANT TO BE A NUKER TOO! (*cryes a river*)
Skyrim won't allow you to be a nuker?
...I 1-shoted a Ancient Dragon with a dagger the other day. Skyrim allows "nukers", it just doesn't allow magic users anything but knock-down-drag-out brawls.
