Well with the recent update, it looks like you are required to solve arch finds once you have 200 items.Or it will not allow you to loot the new finds. Therefore, you can't gain xp, lol So what that means is you'll have to skill up. After you hit 300 you can no longer gain xp in the old world zones. So I guess you could still gain some xp, but it won't be as good since you have to skill up now. It was good while it lasted lmao
