so if i get backstabbed its definitely the fault of the pyro on my team for not killing the spy that i wasnt paying attention to
also taking the time to look around you, takes...uh, not time at all
and sure if by half a second you mean you run by someone and shoot your flame at them to make sure they're legit, but it takes a little bit longer to go out of your way to douse every possible person with flames to ensure they arent spies
when i play pyro, ill check people that i pass close to, but im not wasting my time trying to set my team on fire when i could be doing what im supposed to be doing, taking out the entire other team
