I would say the reverse -
You were able to jump from fighter to gv to buff seamlessly.
Now you require modes or extra buttons.
E.g one button toggled between he/ap for GVs and bombs/rockets for jabos, not any more, you now need two.
Try mapping "fire all" to a single button and drop bombs. It doesn't, you now need to use the 'B' (or whatever) key.
Sorry they have taken an easy to use UI and just complicated it. (joystick/mouse settings).
Personally I can't even see the reason for it.
The new graphics are OK, but the underlying changes have just made it even harder for newbies to get started.
I would have gone with new look minus the joystick/mouse changes, but hey thats only my opinion.
