The coloring should be changed making the blue in the non shiny white/silver in color as the D.Bisharp is based on Cyclone Joker form of Kamen Rider W. and the Shiny one is based on Luna Trigger form of Kamen Rider W. It does not make sense for the Mega to abandon the theme completely.
I would have wanted cooler designs and not a fat centaur. I actually want them to abandon this design and complete the theme.
