It's true that Bandai doesn't care about making the same character in different lines, but dear mother of God, it still makes no sense.
These model kits would be hotter if they released 17 and 18 in their Super outfits, and just focused on different characters that the Figuarts line hasn't made. This would allow collectors to integrate both lines into their collection, as oppose to making them compete, and forcing collectors to pick just one (because they have the same characters).
Just imagine a Figure-Rise Ginyu Force. Insane.
and there ya go. make the same characters fine, just make them in different costumes. man Id love a 17 in super outfit. hopefully if they make a tien, they make him in super outfit.
