Yeah I mostly played Adept to get used to the game feeling "Normal" in a sense as far as difficulty.
But lately I'm switching it up to Expert. It's actually QUITE more fun for my Nord. I don't run over literally everything in my path!

Plus, any Dragon under "Elder" was like PEH! PFFSHAW! basically.. (Frost, Blood, reg. Dragons, NOTHING to me).
But one I put it up on Expert they became much more fun to fight! Instead of like 5-6 hits dead. ^.^
