A han solo vs greedo moment, cos your teammate shot first
and im glad you brought up that situation yesterday, because the fight was won, and then wave after wave of zombies came in then too.
I think one of my reasons for the +1 is the cost of sending in these waves. Currently with half price not on, a rebel loadout is close to a million. Whereas police and Poseidon (who already have numbers on their side) can just throw bodies at any situation(for little to no cost), and if it lasts over 15 minutes they’ll inevitably win due to them coming back over and over.
