I actually wrote a thread about this very subject. I'm from the point of view that the biggest problem is people trying to fit themselves into pre-perceived character archetypes that are from the old D&D era. You can create a very fun and entertaining magic using character without falling into the old "I am a wizard and therefore must only revolve around throwing fireballs at squirrel's (poor squirrels)." The disscusion became very heated. Lots of people taking a strong stance on one side of the fence or the other.

Read it.Your argument was totally flawed. No one thinks mages should be able to fight the same way as warriors. People are saying that magic should at least be viable, whereas it has been castrated and mutated into something that doesn't even resemble TES magic anymore and is only viable if you use exploits, kiting and tonnes of potions. Of course mages shouldn't be able to go toe to toe with a warrior, but they should be able to take them on in a battle.
If there was a way for people's PC's to fight each other there is no way a mage would last even one minute, even using exploits and summoned creatures. Magic is just woefully inadequate. Using it is a chore. Take previous TES games, pretty sure a mage PC could give a warrior a damn good fight, probably win if they had made the right spells (yes the biggest travesty in this game is the removal of spellmaking, and as the reason given was to prevent OP characters, when we end up with the Smithing, Alchemy, Enchanting synergy making warriors supremely OP even though they are pretty OP even without it, makes it seem pointless to remove it).
In effect, no matter how well made your argument was, as it was from a flawed viewpoint, it doesn't really matter.
Reintroduction of spellmaking could go some way to improving this game. Too bad it will never be in.
