In Diadem, even if you're gathering a level 10 item, it will give you the EXP gain of a level 46 item, if you are level 46, and that is all whilst bypassing the need for gear. So when you say, "You may as well be in one of over 2 dozen overworld zones to gather" - I am going to vehemently disagree with you.
and, no, there a plenty of places and duties that can give plenty of time to do other things like Diadem whilst gathering.
