IRC is the where we all idle and hang out at, so you'll get 'better' responses there.
I don't know, but this thread seems more active than individual character forums.
I have some good working knowledge of Ciel, tinker with Warc, and only know Kohaku from an opponent's perspective, but go ahead and shoot questions/post replays. If I can't help you, I'm sure we someone else can, or at least we can refer you to the Legendary Godly Japanese Masters.
