I have screen shots.... masses of dead bodies... a whole pack of laborers standing there. USUALLY i have noticed that the guy with the banner will actually loot. but everyone else just stands there.
Marad different story.
They will shoot arrows at the ground sometimes. other times 1 or 2 will loot (thats 1 or 2 out of one group of guys, again usually the guy with the banner). and other times still... they just stand there.
