The story is great, but it blatantly gets in the way of the rest of the game

I would keep it simple, quest to 15, unlock the dungeons. At each level cap you unlock flying in that expansion's content and the next expansions dungeons. Once you are 80 you can start the EW quest line starting with the first quest released with the EW. This should also apply to all expansions actually, so if you get to SB for example and want to play through that you can.

thats kinda what i was getting at with you unlocking the previous expansions NG+/ unlocking the next area it jumps your story position to the starting quest of the new expansion so when you skip post ARR and get to ishgard for example you have a new quest in the top left corner that show the first HW quest instead of whatever quest you were on
