It's too late for them to start completely reworking the mechanics of the job at this point. That is better served as overhaul changes pre expansion drop. Things like reworking the functionality of Nastrond is extremely unlikely.

What is likely to change at this point?

-Potencies
-Eyes not being removed when BotD falls off
-Dragon Sight being made easier to use
-Mirage Dive having the animation lock removed/reduced

Other than that, I can't see anything else happening. And if those changes did happen I would honestly be satisfied with that. Also keep in mind that if you start reducing jump cd's and adding dive ready to more and more stuff, you will be having to pop mirage dive like a machine gun and LotD will no longer line up with BfB.
