I disagree when it comes to Roadbuster. To me the face of the robot mode severely hurts the tribute and to me its not as obvious. Basically it feels like another character and not roadbuster.

When it comes to body, alt mode and colors, yes it is roadbuster but the face makes all that null the same as how it happened with Cliffjumper.

Most important, they are only proposing 2 extra accessories for the Roadbuster kit (drawn in different angles) and a face replacement for the head. It's no where near as bad as G1 Roadbuster.
