Two basic but helpful tips for you guys: when I first started tinker with my IPH, the easiest and best thing was to (1) disable trinity unstucker and (2) disable backtracking for gold stacks. Bot pathing is very good now, and I have not needed trinity unstuck feature while botting with the WW barbarian's high mobility. So why disable it? Wallers, Vortex, Jailer etc. mobs had a tendency to trigger trinity unstucker. For a brief moment it causes combat to stop and that causes IPH to drop due to deaths, etc. Secondly, I don't want my bot to turn around even if 10 stacks of 25,000 gold magically drops. Running past a few stacks of gold does add up over time, but my priority is keeping WOTB up and continually clearing the dungeons for more loot/IPH. Make sure to have pickup radius on at least one piece of gear if you are doing this.
