Im a console player so i understand this is already possible through mods and has probably been thought of but what if we had a Dlc that added a spellmaking altar where you could craft spell tomes using the enchantment and magic skills. You could pick type of spell, area of effect, projectile, bring back touch spells! Etc... You could pick or mix up to two certain spell effects and your enchanting/magic skills would determine the strength of spells. You could name the spell, designate which school it's a part of. Use the tome like any other and there you go. It could solve the problem of spellmaking and damage scaling not being in the game. And it adds more depth to the crafting system.

I like this idea.
