As the title says can you run both GB and HB at the same time? If so how? Because when i try to open them both, only one of them lets me login and the other says restart HB/GB because one of them doesn't attach to wow. Basically i can only get one to work at a time.
You should start a second WoW first. I don't know why you want to start 2 bots for one WoW at the same time.
I don't think you can do that with GB and HB. The best you could hope for at that point is to find a decent herb farming profile for HB, which will likely be old world since HB doesn't fly.
