Man, why aren't there more Vex crab drives?

Well, we're only allowed 10 motors/servos per robot, and crab has to have each wheel independently driven. On top of that, we need two motors/servos to turn the wheels for coax. There are a few teams that use 6 motors on their drivetrain but not a lot, as most of them use their motors to build manipulators.
For this game I'm even contemplating using 2 drive motors geared for torque, just because I need all of my motors for the manipulator(s).
