What's the point in botting in BG's? Or anything PvP or PvE.. Just seems like you're not even playing the game at all at that point, so why not just cancel your sub and move on. If you don't want to get banned, don't bot.
All i do is gatherer on a 2nd account and I've been using wrobot for 6 months now farming 12hrs a day with no ban. On a lower pop realm and running in prowl all the time.
You could always use HB, heh.
