Anybody doing these? It is by far the closest thing to d2 single player pit/at runs that I have seen in d3. Been doing these with a WW/Rend 5 piece IK/Skorn barb consistently in 4- minutes. About 8 elites per run. Note that the checkpoint allows for not losing any time transitioning apart from the 4sec tp at the end of the run so that you can leave game. Also the map is practically static and there is minimal back tracking.
