Intentionally losing so your friend/guildmate in the other team wins and gets infamy.

 

But the chance of you being in the same game with a guild mate is very small... And there's still a 50/50 chance that you're on different teams. So how would it even be worth it?

 

I've seen it happen, I think there was a video on the forums a while back showing it... Some people live with the sole intention of annoying others so they don't really need a reason they are satisfied making you angry...

 

In higher levels, it’s easier. When 10 players of the same guild with same infamy take a match at the same time, it can happen. And it wasn’t every match, but very annoying when it happened

 

I have even done it with my siblings at under 1k infamy so it's very possible

 

Its easier at the higher end with a smaller player pool, we often attempt to queue together as a guild (for fun, not for wintrading!).

Wintrading is useful for people willing to cheat, for example if you end up against 2 guildmates fleeting that are both working on a difficult weapon quest. Eat as many Standard Mortar shots as you can, and then proceed to die. The main problem, aside from people with questionable moral, is that infamy is pretty pointless for almost everyone in Nightmare.

 

Nice quad kill
