Not weird.
Do you remember back when the xbox360 came out, and microsoft was touting the "Games for Windows" campaign? Basically you could play on your 360 against/with PC players. What they found out, was that the mouse is a much more precise aiming tool then--well--pretty much anything. Even with a bit of auto aim, PC players were owning the 360 players so hard, that it wasn't fun.
Simply put, there are very few Human Interface Devices that are as accurate at a mouse.
Of course, a mouse and keyboard doesn't give you nearly the same feeling of flight as a joystick, throttle, and pedal set. Furthermore, I'd like to see a mouse and keyboard user navigate as well as a HOTAS user. To the best of my knowledge, all top racers are HOTAS users. I guess what I'm saying is, gunnery works much better with a mouse and keyboard, while navigation works better with a HOTAS. Mix the two in 2.0, and you'll be a force to be reckoned with.
Speaking of, I'll need some turret gunners for my Tali...
And a terrible pun for a ship name...
