I usually play killer, when I decide to play survivor the following happens:

1. Killer spawns like right next to me... hey look a hook for me
2. Killer wants for farm... boring
3. You loop the killer for like 3 seasons of your favorite show and your teammates maybe get one gen done.. yay
4. Your teammates disconnect faster than you can say "Not the police station again!"

yeah... I better stick to killer.
