mAc Chaos

Yeah, I've only been playing him for like two days. I have someone to play offline against too, so I guess I can only get better in time. I read through the entire combo thread and did every single one, the main problem I'm having is landing them in-match and actually getting into combos. Is it worth it to go into 214B off of 5A or 5B, or would the damage output be too bad?
