Yeah as a human the only thing i really get mad about is the selfish humans that go for kills only, and don't cover. Like on the map turnpike if you are aware there are two ways to the ladder spot. one way is the ladder, and the other trashbin. Most of the time when a zombie is going up ladder everyone is spamming lr at the zombie while another zombie climbs up the trash can, and kills all the humans >.<... Then theres the asshats that watch you get flanked and don't cover you, but thats another story
