Didnt need 30 mins. Didnt work, pulled the boss and killed him. Might need a little adjustment? ^^
Can you open the xml file in editor for me, and tell me if:
<AvoidMobs>
<Mob Name="Summon Enabler Stalker" Entry="53488" />
<Mob Name="Flesh Hunter" Entry="15335"/>
<Mob Name="Qiraj Warrior" Entry="15387"/>
<Mob Name="Swarmguard Needler" Entry="15344"/>
<Mob Name="General Rajaxx" Entry="15341"/>
<Mob Name="Major Yeggeth" Entry="15386"/>
<Mob Name="Colonel Zerran" Entry="15385"/>
<Mob Name="Major Pakkon" Entry="15388"/>
<Mob Name="Captain Xurrem" Entry="15390"/>
<Mob Name="Captain Drenn" Entry="15389"/>
<Mob Name="Captain Qeez" Entry="15391"/>
<Mob Name="Obsidian Destroyer" Entry="15338"/>
</AvoidMobs>
is near the top of the code?
Also, what combat routine are you using? I would suggest sticking to Singular... other CR's may play with targeting a great deal.
