My main reason being, I really need to return to obtain the Nahkriin mask as I (as well as many other players) seem to skip past him just to survive and run into the portal to Sovngarde.
I really think this should be addressed in some sort of patch/update etc. for all of those people who really want a high level of completion. Getting all of the masks seems like a real fun thing until you realize you will never be able to go back and pick this specific one back up. And the same goes for those who did not receive the shout in the dungeon as well.
Furthermore, is there anyone who has discovered some way to get back to Skuldafn on console?
I play on PS3, and sometimes I really wish I had console commands so I could return.
What do you guys think?
