I can teach you the basics and advanced maneuvers with general game stuff but I can't help you with Leixia. I know a top Leixia player who can help you with her though. (Mind you, I'm more competent in Calibur than DOA as it was my first fighter)
I'll type you up a couple of paragraphs on the games basics and advanced stuff tomorrow if that's okay with you.
8Wayrun.com. You're lucky; they just renovated the site! would you like us to have a conversation there or on here? Either is fine for me.
