I'm not denying that they use enchanted weapon bit it's common, even the enchanter at college says that they use enchanted weapons and armor.
About the court mages though, good point, I forgot about them. But do they join the battle? As I've posted several scenario above that shows disadvantage without the presence of mage on the battlefield.
1) Alright I'll concede on that one, they have cour mages to tell them that basic things anyway.
2) Until they resurrected the nords themselves.
3) Fair enough.
4) Fair enough on levitation but dispel can be used on many others, such as reflect damage.
About the frenzy poison, mage can counter that with calm spell.
Well, I'm not about to say NOT having a wizard is an advantage. It's simply not an insurmountable advantage. Calm spell effectively removes the target from the battle, at least temporarily. Also, we both know that they aren't one handed masters, and they aren't throwing thrall spells around either.
Regardless, this is a silly thing to discuss. At least the specifics of battlefield tactics. Would make a good scene in a movie though, I think.
