I highly doubt the milling "bots" were using HonorBuddy.
I've botted milling/production for years. Hundreds of thousands, maybe millions of herbs. All done with a simple Autohotkey script. The goblin community uses similar AHK scripts.
Milling 20 at a time simply turns a 4 hour session into a 1 hour session.
Code:
Loop, 5000
{
ControlSend,,-, ahk_id 0xd7079c
;ControlSend,,-,World of Warcraft
Sleep, % rand (2300, 2400)
;Sleep, % rand (3600, 3800)
}
That's the little script I wrote for mine.
When I had more than one WoW going, I'd use the first line, otherwise I could just use the second.
I can use the same macro for crafting glyphs (or anything else, I suppose) if you use TSM. I just bind the '-' key to my TSMcraftnext macro in game.
