In my opinion, Jones drew out a more unlikeable side of DC. Say what you want about never understanding the hate, but I definitely felt like he had a chip on his shoulder and went out of his way to push himself as the "good guy", and I can see why that can be irritating to some.
Now that Jon is out of the picture, DC is acting a lot more like he used to during his Strikeforce days, which is when I really started liking the guy.
