I usually try to single-player the game as much as possible. However, now with all the content this year having an interconnected story, I want to get the 2 dungeon dlc this year.
Do you need to do these in a group to have any shot at all or can you do them alone?
They mentioned a "hard mode". I assume that's optional somehow.
If you can't realistically solo, I hope and assume it's not hard to find a group, especially after these just come out.
