Since the new patch, the bot just stands at the entrance and doesn't move at all when a bg starts 

Im not fully sure, but there was a discussion about disabling BG-Botting with WRobot, since its waaay to risky and almost in every case 100% Ban. Maybe someone knows better than me.

There isn't official word yet about stopping BG botting for retail but it sure is way too risky

Also i'm not even gonna try if it works for me because i'm not going to risk my account with something that is guaranteed banhammer

Did they add something in the new patch that makes it riskier or something? Because I've been bg botting with this for at least 2 years and have never been banned

Lucky you then. Most bg botters been banned within months
