therein lies the problem. Wheelspeed is king in Mud, and if you have to limit your RPM's, that is an issue. I've tried high range in mud, and the snotty, sticky, clay based mud we have here will burn up a clutch in a HURRY...if you stop. If you hammer through, its no issue at all! lol
A lot of times, there isn't a bottom either...you just keep digging until your on the frame.
I'm very well schooled on mud believe me. And yes only being able to hit 3K RPM's is a issue but I really can't think of too many time I had issues. I never used hi range because I had the 4 popper and it didn't have the power for that.
Snow is the same some times where you need that wheel speed to get up on top of it.
