Yes. I am currently using it to level herb on a lvl 80 from scratch. The only zone i have not been able to use it do to a crap ton of trees and other land issues was Duskwood.
My setup:
Windows 7 Ultimate 64bit
WOW US
A few things I have noted to use this on a land mount.
1) You have to use the included waypoint tool to create your own paths.
2) Change the value in the waypoint tool from 50 to something much lower. (I use 10)
3) When pathing around anything that my get your toon stuck, (trees, fences, poles, etc...) make sure to turn wide like your driving and 18 wheeler
4) Once you have created your path file make sure the file has the extension of .ini if not you can just edit the file name and add it.
5) for low level zone you will need to add the names of the herbs/ore in the 'Farm' tab. (otherwise it will not know to look for them)
Other stuff you should just do.
1) make sure you go into your keybinds and setup the keys for 'interact with target' and ' interact with mouseover'
2) got into interface options, then mouse, and select move with mouse click.
3) make sure you use 'Loot via memorywrites' (if you dont your toon may not go back to loot your herb/ore if he/she has to fight something)
Over all this is a great bot. I hope my post helps a couple of you. If you have issues post a question, I'm sure someone will try to answer you as best they can.
