Its been some weeks now since I found a 'blue shirt', not an ordinary 'shirt' but a level 20 item. But strangely enough, I never found another. Stats? Def 3, so that's not that special. And now that I think of it; I collected two belts with def 14, but lately never found one with def more than 10. Are they obsolete instead of new??
If you look at the large map, its four times bigger than what we can access now, so many expansions are still possible. We just have to be patient
