No, and open carrier will not wear out fast. They are actually one of the safest carriers to use to prevent damage to not only the carrier, but also everything else inside the differential (i.e. ring and pinion, axle shafts). Due to the design of an open diff, it limits bind by shifting the engine's power to the wheel of least resistance/traction.
The problem with an open diff is that it shifts the power to the wheel of least resistance. When in the mud, you'll get NOWHERE! In the rocks or other off road situation it's not as bad as long as you have both wheels on the ground. The instant one tire comes off the ground, that axle becomes useless at propelling you forward.
