User blog comment:Jimeee/Skyrim 1.9 beta update adds Legendary difficulty and raises level cap (Updated Apr 8th)/@comment-31.53.78.34-20130413223835/@comment-177.72.248.8-20130414143600

Agree. Foes using spells like paralyze, conjuring Dremora Lords or weapons and armor with high smithing levels would be nice. A good A.I. would help too.

Legendary difficulty is viable if you play as a tough warrior or a stealth thief. Playing as a destruction/conjuration mage is almost impossible.

So, legendary difficulty only means that you have to hit more and not having a better strategy. It turns the RPG game in a action game.
