Bah, just make sure your combat routines are up to spec and set up your botbase like this:
Advanced
Custom Scripts Path - (point this to a folder where you can store custom scripts, Honorbuddy\DBCustom would work)
Tank In Random Groups - FALSE - VERY BAD IF TRUE (this would group you with non-bots)
Use FrameLock - True
Loot
Loot Mode - Always
Mail BoE items - True
Maximum Vendor Item Quaility - Poor (sells greys)
Minimum Mail Item Quality - Common (mails everything else)
** Note: my bot group includes a disenchanter so I don't accumulate lots of BoP blue gear. If your group does not, I'd recommend setting Vendor Item Quality to include blues otherwise your bags will fill very quickly. This is also a good setting if you want cash over enchanting mats.
Misc
Combat Movement - True (for healers only, to move to LoS if needed, I tend to leave as false for dps classes)
Following Distance - 20
Hearth on Vendor run - False (if your toons are parked by a mailbox/repair vendor, true otherwise)
Kill Optional Bosses - True
Pickup Quests - True (many quests are automated, some may require some manual input - the second sword in Scarlet Monastery in particular)
Port Outside On Ghost Sighting - False
Party (this is the important bit)
Leader Name - set this to your tank toon's name. Leave blank on the tank.
Party Member Names - on your tank only, click the ... and enter your healer and dps toons' names, one on each line. Leave blank on healer and dps.
Party Mode - set this to Leader on the tank, set to Follower on healer and dps toons.
Vender
Inside Instance Repair % - 10
Minimum Free Bag Slots - 3
Outside Instance Repair % - 50
Outside Instance Sell % - 25
Port Out To Buy - False
Port Out To Sell - False
Most settings are your choice, just pay attention to the Party selections. Those are important.
Make sure AutoEquip is enabled and properly set up, especially if you have an enchanter.
Make sure your combat routines have movement/facing enabled.
Make sure your combat routines have targeting disabled.
Have fun.
