Every time I have attempted this infuriating heroic on Dromund Kaas with a group, another group runs up and activates the drill while we are fighting the rebels, thus spawning another group of rebels right in the midst, and confusing everyone on which guys to kill, as some are recognized hostiles and some are greys, and they all attack you.
It's ridiculous - what are those two other drills in the area for, *********** decoration?
I even made an operations group to get everyone in the area into one place so it doesnt happen, and what do you know? Some idiot runs up and activates the drill.
