make sure extend trash pack range after combat is off.
As well as turn force kill summoners off. As both of those will cause the bot to kill odd mobs. Though the summoners one can be useful.
Beyond that its a matter of your spec and combat routine prob. As you haven't given much info such as what your doing/your spec/class so forth people can;t really help much. As your classes combat routine can effect what being targeted. But targeting with the bot has always been of at times esp early season when people are using new builds.
