Continuing off where we left off.
Even though I made my suggestion, I'll add onto this. Because a class requires a bit more micromanaging than a perk tree. As said coming from a DnD background, skills like Wisdom and Intelligence are necessary for mages.
So you're technically correct, that you can create and stick to a class in Skyrim.
Where you're technically incorrect, is that there is more into building a class than say a simple perk tree. It means, as I have explained before, I like to modify my numbers. I like to mess around with builds and skills. And in the end, a wizard will play the same in Skyrim than say Oblivion.
In Oblivion it was easier to build different specks. With the Degration spells for Destruction, I didn't necessarily have to focus on simply destruction magic for my main source of damage. I could degrade someone's armor or break their sword.
In Skyrim we're limited to a very select handful of destruction spells and most of them are, elemental. And I've never been too big of a fan of elemental wizards. My favorite wizard in Kingdoms of Amular, used f-ing Chakrams because da[censored] is awesome. In Fable, I made a Force Mage which is raw energy.
In Oblivion I made a mysticism and conjuration mage.
It's technical to do so in Skyrim, but with the limited spell variation, it makes it difficult to run a playthrough without some destruction
