I'd put emphasis on the word "good". This was a long time ago so the details are sketchy but when I fought NDJ all he did was the same thing over and over again every single match. Wanting to see whether or not people were complaining about this guy, I googled his name, and found his YouTube account which apparently at the time showed him doing exactly that - exploiting (and I use that term loosely) the hell out of Jax and then accusing the people who didn't stick around to be noobs for not knowing how to break out of it. The guys who do UltimateMK's combo videos would have trouble getting out of what he does let alone the majority of people on the PSN. Personally, I've gone on record saying I don't play fighting games like that, I believe in giving people a chance to breathe and that doesn't mean that he has to do it too, but to upload a video everytime somebody quits on you for doing the same thing with the same character over and over again... He just comes off as childish, the combination of his playstyle and attitude gives people the impression that it's the only thing he knows how to do in life. The whole derogatory name doesn't do him any favors either, IMO.
Of course, the videos of him rage quitting never got uploaded to his account. Though I think you can find them elsewhere.
Edit- Here's some, /watch?v=K0FJNcxpNWk and /watch?v=wGHMJYUzka8 . I know there are (or were) others cause his actual PSN name was either divinefist81 or devinefist one of those two.
