I had this idea to take a Destruction/Conjuration mage (also Alteration, Alchemy, and the most important one, Enchanting) and put him in heavy armor.
Now just hear me out... In the beginning part of the game, that wouldn't be such a great idea. You'd miss out on all of the best mage gear. There aren't that many sets of Dwarven Armor with reduced casting costs super early in the game. All the best mage enchantments come on robes, 'n s**t.
But as you level up work on Enchanting, you get to a point where you can indeed put mage-friendly enchantments on heavy armor that are on par with (or better) than most pre-generated items found in the game. So in the mid-late game, this would seem to be a great idea. You can dress up in the heaviest armor type and enchant everything with reduced casting costs until you're practically (or actually) casting all your spells for free.
Right? Or am I just talkin' outta my a**? Is there any other in inherent problem with mages using heavy armor in this game? No casting cost penalties or b******t like that? Anything wrong with my idea?
