I'm a pc gamer at heart. I use a board/mouse combo on xb1. I've been bested by controller users. It does not lead to advantage whatsoever. The games movement speed is based on in game settings. Maxed destiny sensitivity is 10, with a controller or a mouse it moves the same. If it's cheating. Than so it scuff and xbox elite controller. And the controller mapping option in xbox. It's not wrong. It's just what your good with. There is a limit to what the game can do. This limit is not broken by a mouse and keyboard. So I map a button to hit jump and stab. You can do both too? Maybe I nap a button to hit zoom-delay-fire this is no different that using a controller and doing it myself. It comes down to player skill. And what peripheral the user wants to control the game with. IT DOES NOT GIVE AN ADVANTAGE. Edit. Ok. So it's an advantage for pc gamers. Who have 1000s of hours worked to the mouse for a great shot. Fair. Additional edit. Yes. It's better mouse and kb is better. For stoping movement across the screen more precisely. Fair. But moving faster. No. Button mapping ? Guess what xbox one has it. Do with it what you please. However. This argument is now invalid. If you will direct your attention [url=http://www.extremetech.com/gaming/210778-microsoft-will-add-keyboard-mouse-support-to-xbox-one-for-gaming]here[/url] you will see that they have planned to add key/mouse to the DEFAULT XBOX ONE as in. No additional hardware required plug and play. Ha. Hahaha. Ha.
