Keyboard and mouse is a crutch plain and simple. I would not call it "cheating" but it is just as bad as a mode controller. Anyone who uses keyboard and mouse is just showing that he/she is unskilled in true console gaming because console gaming is a test of controller skill. My example is this: TRT and other types of steroids are legal to take under a doctors supervision but if that person taking the "legal" steroids are competing in professional sports it gives them an unfair advantage. It's not technically cheating but like I said prior, it's a crutch and a huge one at that.
