I’m doing co-op with my spouse, and we’re opting to nearly complete every Altar of Lilith, side mission, and explore every area before moving the story along. As a result, we’re both level 56+ and are easily taking out most everything on World Level 2.
Are you folks doing something similar? Or just going straight to the main story/quest without detours?
You gotta rush the main quest to act 4 at least so you can get your mount!
