I couldnt find any good asnwer yet, but is there no way to access endwalker without having to play 100-200 quests from the expansion before ? I just finished heavensward, and while it was fun , questing all day alone isnt to amazing, but playing dunegons is useless as you would out level your quests, which you need to do or every content is locked.
Is that just reality to acceept?
