This did not work for me at all.
I read through your instructions carefully 3 times. Then I fired up WoW.
My setup is that I have 2 accounts that are linked to eachother and then a separate booster account.
I loaded all of the HB clients with the quiesting bot. The booster got the deadmines profile and the RAFs got the auto loader profile. They have started in Stormwind every single try but it seems that I have some issues with the "nearby players detection". One of the many times I tried they all went to meet outside the house of the deadmines cave. Then the booster just ran in and the other 2 just stood there and didn't do anything and their bot was complaining that everyone was not there.
Then I restarted it, everyone meet again and went down succesfully this time. But then one of my RAFs got attacked by a mob inside and ignored it. This caused to fall behind abit and the the other 2 bots went into the instance and as they went into the instance the one that got attacked went back to attack the red mob and then every bot complained that everyone was not there.
The third time everyone actually went into the instance but only the booster and one of the RAFs continued in. The other RAF stood there just inside the instance and the bot was complaining that not everyone was there :/
