Unfortunately, underwater combat is stil absent. It kinda makes an Argonian's waterbreathing useless.

Tired of people circle strafing you and going for the backstab eh?
Welcome home. Just try to play a different character than you have before to keep things different. Another thing I like to do is not go straight to riverwood or whiterun. My current character headed straight to markath and has not been to whiterun in over 20 hours playtime.

Hahaha yeah I year that's a real problem... I play offline, though. I *DO* however think that Skyrim could benefit from some type of way to "merge worlds" like Dark Souls had... it'd be tough to do properly, but if done right, it could be VERY cool.
