Have you ever looked at how a Mouse and Thumbstick actually read movement? They are not equal.

So while yes, my preference is KB/Mouse, IT IS superior in a game of this design. More so in an FPS, but due to how Most MMOs play, they're very similar to an FPS. I won't knock people for wanting to use one or the other, or for wanting to click skills or keyboard turn. However, one is clearly better than the other for any given task.
