Im a completionist. I got every achievement within 10 days. 350 hours on my main. Have every item obtainable and every house. All shouts, spells, and weapons. I'm only 63. At 81, you have everything maxed out. There's no point to go higher.

Sorry if I sound like I'm complaining. But you wouldn't believe how many people used to complain about it being to easy at 81. My jaw was on the floor when I read that.

I am level 81,have all achievements,all houses,all items, 673 hours on one character and I have completed all available missions and have so many infinite side quests done that it takes me over 2 minutes to scroll to the bottom of the page

No one knows for sure, those who say no are stating something they believe. Its all assumptions.
