Shouldn't be in PvP only PvE it's just too easy to exploit. If you choose to use a controller that's fine, but why should you get extra help for picking that? A decent mouse... Any mouse is better than a controller. You could buy something for $10 and honestly be okay. Its a much better experience to play FPS games with a mouse and keyboard. I grew up on consoles and mostly played shooters until I switched to PC about four years ago. Now I will NEVER play a shooter with a controller again! Don't be intimidated by switching. All your skills will transfer over and your aim will greatly improve. Its such a better experience and couldn't recommend the switch more.
