Just gonna chime in here, I've been told the game has to swap input methods exclusively between controllers and mouse. Guess what, we're unable to make use of hybrid controls this way. All because of the sticky aim and bullet magnatism you guys have been arguing over for 82 pages of forum messages now.
Say what you will, all controller players at the moment would be better served under hybrid controls, controller in one hand for movement and mouse in the other for aiming. If you haven't tried it before boot up a game that allows for simultaneous input (I use it for emulators. PS2 and Gamecube mostly) and you'll be blown away... or, err, in this case it's your enemies who'll be sent to the next dimension.
Oh, and on topic. I don't believe any control method should get benefits that no other method has. It should be the player's ability to manipulate their controls that decides their performance, no artificial help. That just seems like common sense to me. At the very least it should be a server option on the PC side of things... of course, we'd need dedicated servers and a browser for that, first.
is good and hurts no-one.
