Twice last weekend our party was placed in a FOV change hacked lobby. Of course we all got the infection and both times the lobby booted us immediately. The remedy for getting rid of the FOV change is of course to back out of the game and come back, but this is starting to get annoying.
If you can't solve the hack, maybe give the FOV change as an option to console users?
Then those who want it can continue and those who don't won't be bothered with it (I hope). There is probably more to it than this. Is this too simple a solution?
