As much as I dislike MW3, to say it has a 'smaller size playerbase' is pretty hilarious. It did not have a way to change FoV until it was added through a 3rd party program some time after launch. Pretty sure if you google "MW3 news" you'd be hard pressed to find articles of people vomiting all over their computer screens and their eyeballs falling out. And that is with an FPS.
Yes, it's an issue. But you guys are exaggerating it like crazy. Jesus.
