Me and my buddies used to pull this prank, where we got all our guild members on a specified area on the map (usually deserted) and form a circle. They would enter my house and wait for my mark
Then I got either some cocky little **** or random noob to follow me to that area. I told them to stand in a spot (which was in the middle of the circle) and then I would close my gh and 10 of us would appear out of nowhere and trap/kill the guy.
Good times
