Why the recommendation for slotted rotors?

I've had them on one car and know they generate more pulsations in the pedal than non-slotted rotors on the same car. You also have less thermal mass whcih is not a benefit.

What's the advantage? Outgassing? That's not really a thing with pads anymore.

Cleaning mud from the interface in an off-road setting? Maybe?

Get solid rotors.

Offroad is all about reliability. Not weight savings, not designing for specific conditions like wet, dry, dusty, etc. You want the "rode hard, put away wet", version.
