You know what, it was worth it. I enjoyed rolling around in these things in Gundam Breaker, running over enemies to shatter them repeatedly.
Also, in animation they don't spend very much time just rolling around in wheel mode. The mobile suit inside of it is regularly leaning out to do shit, and the wheels split apart, too. A picture makes it look dumber than it is, because it implies that it just rolls around. In practice the animators thought up some interesting ways to use them.
