I agree that there should be a sensitivity setting added, but I really think you're judging it too quickly.
Galactic Starfighter was a huge fan service. Out of all of my friends, I can safely say: I am the biggest EA hater, but what they've done here is excellent. Not only did they add pvp support for space fighting, but they changed the whole damn thing! I was absolutely overwhelmed the first time I entered my ship to fight for the Empire today, but I play the game for challenge anyway, so the tougher the better (in honor of Sith Inquisitor).. The controls feel so complicated at first, but once you get your orientation straight, you can make your ship dance! Don't take this the wrong way, but just because you're bad at something at the moment doesn't make it a bad system. Play a couple more games after doing the tutorial, and I promise you, you'll start to enjoy it slightly. It just feels so Star Wars and respects the genre.
I personally love this new pvp mode. Thank you, EA/Bioware, for giving me a reason to come back to your game after months of not playing.
