To all the people saying that a controller is absolutely necessary: it's not. I have both the Xbox 360 and PC versions (bought the PC version for the DLC coz it was on sale) and with DsFix and Dsmfix I actually find the keyboard+mouse control better - especially when aiming with a bow. I also find certain commands (like forward+attack for Kick) easier to do as well. The keyboard+mouse control has a bit of a learning curve learning all the mappings but it's usable once you get used to it.
I think it's a testament to how innately bad controllers are for aiming that I find aiming with a mouse in such a terrible port still better than with a controller.
