The current method for spawning the Rock Cam is by pressing on the left joystick for a second. It's a problem for people who sprint a lot, since we constantly have the thumb on the joystick. So just gripping the controller a bit too strongly can lead to the Rock Cam spawning right in your face. It's a big problem in competitive matches!
A good rebind would target one of the measurement buttons (the ones used for T-pose) instead of the joysticks, and have an option to choose which side to use.
