Null is right, you guys are wrong, the funnest part is killing people, ruining their shit, and just causing mass chaos.
people in Stella or elsewhere trying to kill a Bastion? help the Bastion, kill them, use flame nades to force them out of positions of they get gunned down by the bastion, just be a complete and total villain, then plant mines under their corpses, plant gas mines everywhere , wait at the last gas mine and kill the guy going to shoot it, use 50 barricades to block off extracts, go into friendly lobbies where they all stand around slapdicking and throw Trailblazers into the group, double back around and claim you've found the "rat" and lead them into the pit of mines.
