One thing (well among many) that CIG seem to ignore on every occasion is their take on the mouse controls and it's zero order movement. They only talked about the gimball weapons, and instead of bringing mouse in line with other controls, they seem to want to complicate things more by giving certain other controls some sort of direct aim input.
It still doesn't change the fact that mouse/kb is just point and shoot atm, and it's really all that's needed at this iteration of AC. Fancy flying is only useful in free flight mode, in combat it's redundant.
They have a lot to do in order to make the game really controller agnostic.
They are simply not going to do that. They are creating a P2W game and are probably sponsored by hardware manufacturers to go that way. Instead of removing zero-order mouse controls they have stated that everyone with head-tracking devices will be able to control aiming just as you would do it with the mouse. And in case you do not have such hardware you can play with joystick and mouse.
