Yes all the spells are there in SKYRIM but how about the weapons and armor on Warcraft or beasts it would make SKYRIM more exciting & there is one spell that's not on SKYRIM. Summoning a water element or changing a tree into a treant(a tree that can fight) or summoning a tornado to help you fight a group of enemies or how about the auras( eg: true shot aura which increases your & your followers arrow damage) etc...
