Dont understand

I don't understand why teams keep lining up on spike defuser sure it works in a smoke so u protect the defuser and make enemies think they killed the defuser but dry lining up is just restarted and every team keeps doing it for no reason it rarely end well u always prefire the spike and then u get a free 2/3 kill bruh

cuz a lot of the times they need to be in a line to see the attackers
