Why do they do this?

First game yesterday put into Horizon. First thing I noticed there were only 2 on my team. Wondering what I got into I started moving around. The other team had 6 players - 5 of them (fr4om what I could tell) were just jumping high and spinning with their
sniper rifles. I am assuming this is to get an achievement in the event they did kill someone? Me and my other team mate came back (I am assuming he had just joined also) to win 75 -74.

So is tis an achievement thing they are trying?

Why do they choose to do this?

The problem is they know most of the community only cares about their k/d and could care less what their w/l is so they dont change it. The irony is I think most of the players became jaded to w/l because of the auto loss problem and joining games with
no possibility of winning..

 

Why do they choose to do this?

You don't get a loss when the server connection times out, just when the host dashboards.

 

I should mention the score when I joined was something like 47-12 in their favor. So I figured they stopped trying doing whatever they were attempting.

 

Your team probably dashboarded to get out of a quick scoping lobby, meaning the whole other team was "sniping"/QSing. I dunno about cheevos, I dont chase em.
