I know what you're talking about. I was in Stormwind testing out the Blood DK file, and it works great. I tried with -- and without -- scroll lock (not NUM lock like last time, lol), and it still finds its own targets. As I walked by each training dummy it would automatically select it and keep its combat stance, as though I clicked Auto Attack, and it even went as far as to Death Grip critters (level 1 critters that are running around). In order to make it stop attacking anything that was attackalbe I had to stop the bot completely.
Oh man, that is hil-AR-ious! But so wrong.
So I've disabled that bit, let me know if you still deathgrip tasty critters for your dinner.
