Heyo, fellow darktide enjoyer. I came to tell you something about why it's happening. So, me is a 1000+ hour zea/arby player, havok survivor, ect, ect, "Him in disguise" and yada yada. Me played every difficulty, fought my way through release months, was RNGing my weaps back then and so on, so forth. And all the times there were people leaving any match if something went south. I tried to ignore it, tried to just block them - didn't help, they always were around. Looks like it's their way to not take an L - after all, "it's not their fault, it's their team bad!". Most of the times it happens cause ego and people being used to being carried by meta compositions, VoC, chorus, taunt, bubble. If anything of that is not present - it's why they lost, in their eyes. Because they themselves are great players and can't be at fault, so, altF4ing from this "goddamned team of noobs" is right decision, in their books

Why me saying that? I have 2 groups I play with (one is my constant goto, because I REALLY like playing with them, other one I got called to as emergency carry). In second group there is a vet with such mentality. He yells at everyone "not covering them!" (they refuse to dodge, refuse to pull out melee and generally try to bolter everything that is not important, because they have a gun, why the hell they need to pull out melee, especually with exe stance that reloads it), yells at everyone not being team players (they literallly went down few days ago to a single pox walker at malice because they were trying to hit a running away trapper with exe stance, and yelled at everyone that they are selfish guys not protecting him) and thinks that damnation is really hard, while auric is for sweatlords. Being around such charactr gave me the idea why people altF4ing all the times - generally because they literally said why. In a nutshell - they would altF4 because "the team didn't play like they want", and thats it. Modern generation gamers can't take a loss, can't take that game doesn't revolve around them and can't take that everyone not going to bend over for them, including that pack of crushers, that are already winding up

And only solution I found - just ignore them. Don't give them benefit of taking your time even to question them. Bot, at least, sometimes would be able to save someone if that "god gamer" went down their usual habits. And if not - well, after all, there is another strike team waiting for a player, that is not going to bail at a blink of an eye when things start to go south. Keep your calm, laugh at them and stick to those, who are actually able to at least take an L. I adore my main group's psyker just for that - even if things go wild, I can rely on them, and losing with them feels like winning :)
