In FRC, 16fps for a single speed has no advantages to 12fps for a single speed. By the time you accelerate to the top speed, you're already clear across the field.

You can't use 6 cims in present mecanum drives.

Controlling a robot through 4 independent shifts on a mecanum drive would be difficult.

8 years ago if I told you that in the future, mecanum wheels would be available for purchase to every team at a reasonable cost, you would have called me crazy.
