Why do they leave the match before reinforcements?

Why do so many FTs get out before calling for reinforcements?
There are three patterns I’ve come up with

  1. they were executed as soon as they started, and they faded away.
  2. because my side had no chance of winning. /I gave up.
  3. the line went down.

When I leave, it’s usually 2, but many others apparently leave with 1.
Throughout many games, however, it seems that the people who leave
at 1 are basically executed immediately for not doing the right thing.

Group up, focus , cover.
Don’t you think we should create a place for people to learn the basics first?

They don’t like watching people play.
And if your team isnt really doing shit, why stay?

I agree, stay together, be alert.
But idk, I dont really care if people leave.
