I'm not planning on going past steel in the smithing tree, which means she'll likely never hit the armor cap of 900, since SkyRe doesn't allow you to craft/improve items whose material perk you don't have.
My current character uses Heavy Armor, Light Weaponry (1-H), Block, Marksmanship (Archery), Alchemy and Smithing. What are you planning for ranged combat? Or nothing at all?
Muffle is great even if it's the only spell you ever use, and Illusion in general can turn a hopeless situation into a cakewalk.
