Pandora's Box of Targeted Loot
I think now that Ubisoft has opened the Pandora's Box of choosing your own targeted loot in the Summit that they should just make it a global choice.
This would just allow you to play whatever you want wherever you want while looking for whatever items you are looking for.
As it is now when looking for gear almost everyone I know heads to The Summit. No one has much if any interest in doing any other content for gear. Some people are still doing the Legendary's for the weekly cache but that's about it.
They have announced the "optimization station" which signaled in the end of development for this game, so the logical step would be to allow targeted loot to be selected globally.
