The game as it is now seems unplayable. When using mouse control the afterburner can only be activated by double clicking the right mouse button (no TAB as is usual in other WC games). When using a joystick i have the same problem since the afterburner, roll and throttle are all maped to the same(!!!!) button. Hence it is impossible to make a turn and use the afterburner at the same time (and not mess with the throttle on top of that). Is this a bug? I can't even fathom that this is a deliberate design choice, it would be the dumbest control scheme in all of human history. Is there any way to fix this? Otherwise WC 3 will be unplayable. (NOT going to use keyboard)

You're right about the mouse controls, I just tried it again and the tab and tilde keys are disabled while using a mouse, which is nearly game-breaking. Getting through the game might still be technically possible with just a mouse, but it's got to be incredibly frustrating on some of the more challenging missions.

But those keys should still work while using a joystick. Is joystick+keyboard an option for you, or are there extra joystick buttons that you can remap to tab or tilde? (you'll need an external program to do the remapping, it's not an in-game option)

Well, in principle that works, unfortunately i can hardly aim with a joystick. Its way to sensitive for some reason.
