Most of the people doing this becouse they want to enjoy the game and not do their best / tryhard to not die every 10 seconds trying to win mission. I never was in this kind of group of players, im my self very hmm... Not even tryhard, i would call it diehard... Basicly im one of those who would kill them selves after losing match without getting every kill / objective done. But tbh from biggest part i definitely understand why people are de-threating (de**). Its becouse like i mentioned earlier. They dont want to stress from the game and want to play it with positive energy and chill mood but (and thats why they are de**) they cant do that becouse of us, prople like me so when it sometimes happends for them that they rankup to Gold, they try to go to Silver districts but after few missions they are in bad mood becouse of getting killed so many times and that, that they need to do their best to atleast do one objective etc..., and thats not fun for them. So than the de** comes in place so they just troll the mission to get Silver so they can go back play to bronz districts and enjoy the game again. And this is the point of it... Threat becomes a kinda bigger problem over the years but all the time people were ok with it... Also threat had big inpact on many people started chteating in the game becouse when they went to silver district they wanted to be like all these tryhards but couldnt do that becouse it takes some time to get to point when you can really say "im pro/skilled in this game". So cheats becomes first idea and than closeting and pretending their skill masively inproved overnight.
I think that threat is thing that needs to be looked after to find best suiting ranking system for this game.
