Curse those KSing drones! At least we got some easy heavy kills when no one else moved away quickly. 
I wish I'd thought to grab screenies, but I was too busy chasing them around.
I personally felt really bad about it because I told everyone to gather at Castle in broadcast without knowing about the new drones. After mine and Shadow_Fire's team bapped about 6-7 heavies in a row, everyone else came out to join us.
If you're in the habit of fighting near Castle during the Rikti Invasion event in Peregrine Island, you should probably move it out into the parking lot instead.
Castle has 4 new PPD Drone buddies who are pretty much capable of insta-zapping a full spawn of Rikti Heavies.
