Well, like I said; I always stay if I see my randoms fighting next to me, even if if I get executed. So I guess this is basically what you refer to "a minute longer in a match". But I see no reason why I should stay if I am playing with two randoms that dont have my back. Like people who, after the fight is won and no third parties are coming, loots your lootbox before respawning. If things like that happens, I am out of there.
And I honestly also practice what I preach. For instance; if my random teammate solos an enemy totally alone and kills him just as I arrive to help him, I NEVER run up to the lootbox to ninja loot. Instead I do what I think everyone should do in that situation, that is, to protect your teammate that now probably is low on health and maybe also ammo, giving him a chance to shield swap and heal up. And in return I get a bit annoyed when my randoms do this; just runs up to the loot boxes you just 1v3 solo and takes everything good when you are forced to back off to heal up.
Ofc, one instance of such behavior does not make me rage quit (which I never do). But if I see my randoms doing stuff like that again and again, I finally reach a point where I simply dont want to play with them anymore if I die, its simple as that.
