Never mind, wrong forum.

Why would you post a topic obviously about Skyrim's difficulty in the Series Discussion forum?

Also, I don't know what level you're talking about here, but I have a level 30 mage that still dominates just as much as any of my other characters on Expert difficulty. Mages typically don't wear a lot of armor, so you need to have the sense of how to use crowd-control spells. Paralyze, frost spells to slow them down, things like that. Your goal is to keep them at a distance. Make sure you're using the right spells. Flames becomes obsolete when you get Fireball. Fireball becomes obsolete when you get Fire Rune. Etc, etc.

Because I'm a [censored] who doesn't look at the forum he's browsing.

My mistake.
