hm. kensou, i feel you about switching to an easier character, especially if you've reached a "limit". But even yourself admitted that you don't use the maximum potential of your character (fdc air-stuff, 2d JI teleport wake-up games, etc)... maybe just try to find tons of new, fresh content and work from that. If you truly like Chipp, you can -make- him a killer. Just like Ruu makes bridget a killer, he had to create his OWN stuff and create the highest level for that character.
i think that you know your biggest flaws more than anyone, and with much practice and just working through the kinks of a new style, you can learn to avoid minor damage situations which hurt chipp the most.
