What features from 2042 deserve to be carried forward?

In my opinion:

The weapon plus system is actually quite good and allows you to adapt to different situations on the fly. Maybe restrict it to different barrels (suppressor on/off) and sights, but I like the feature overall.

I also like having more verticality and traversal options so I'd like to keep the wingsuit and rope launcher as gadgets. However I would make the rope launcher function as it did in Battlefield Hardline, creating grapple points that function as essentially ladders, rather than just pulling you straight onto something.
