Sigh, I have to agree with you. The popularity of TW Constructor is pushing 3P's to MP scale combiners. Plus I keep forgetting that Defensor is not the most popular of combiners. Maybe Jinbao will come out with an OSKO, or YueXing with a simplified diecast version, or NBK/WeiJiang with a simplified but improved version. I just hope GT Guardian fares better, but like you said, I doubt it now.
