There might be some stacking issues in regards to enchanting that should be looked at, but I don't have much of an issue with spell casting.

Other than the invisibility thing i thought spell balance was ok. I would love some more interesting animations. Throwing a a little ball of fire that is suppose to do a ton of damage is a little anti climactic.

Nope.It is a silly ideia imo.

TES hav always been full exploits. it wouldnt be the same without it.
