I've seen teams using two joysticks with a mecanum drive system, which seems counter-intuitive to me.
We use 2 joysticks. one is translation and the other does rotation on the x axis. Yes, this could be done with a 3-axis joystick but we didn't feel like buying a different joystick. Also tests with team member's personal 3 axis joysticks usually find the twisting in the direction of the arm can be awkward sometimes, especially if you needed to twist while translating in some directions.
