I am normally like you, will transform once. I think due to constraints in my time available I was just "happy" to ignore everything else. I have three other mp-11 moulds and shockingly I have not attempted much in transforming them either other than Hasbro Acid Storm, rest were Takaras Sunstorm, Starscream, and this guy.
It might be worth taking some pics and post at the defects page like I did. Such a defect is actually major and I need to see it for myself once I get around to play with it again.
