It is true this game lacks truly challenging puzzles, but that is intentional. I can safely say a large chunk of the playerbase is not good at such things and so they try to avoid creating content said chunk cannot complete and then goes to complain about. I'd have no beef if they added such content, would be an interesting change of pace, but can't please everyone. Also, define "new"... It may be in small doses but I see new things (new to FF14 anyway) every major patch/expansion.
