You have to remember Cobra is a purebred Rambot woth a weapon ontop due to the rules. Its very much the Tornado of our time and thus theres nothing really wrong with that IMHO. I consider the drive to be its weapon, with the claw being a fitting adaptation (rather than looking forced)

Draven meanwhile has no weapon, no drive, no useful redundency in design shape, and certainly in S8 no armpur :p (not sure what they changed to, but from what ive heard the team tends to be highly over optimistic)

(Note, when i say redundency in design shape - when Dystopias weapon doesnt work or gets a gas leak, its still a half decent rambot)
