league players aren't innately toxic, they just lash out when things aren't going their way.
you are in a bad spot, you recognize the bad spot, but you see you and your team have nothing you can do about it (entirely due to the nature of the game and snowballing) but wait for the enemy team to either throw the game or end it already. so now you're just wasting time and not having fun at the same time.
that eventually builds into toxicity when one member makes a recommendation you cant help but say no to, saying it wont work, this is what we have to do instead.
neither can agree, and so they start yelling about why the other is wrong, and then they try to discredit their ideas either thorugh my KDA is higher, or you're feeding.
instead of either one of you conceding your point and trying out one another's idea, you stubbornly do the opposite of whatever they say. when in reality you say contest baron, he says free dragon, 5 of you going to dragon is better than 4 of you going to baron without your ADC. instead the enemy team gets 4/5 of you and the baron. but if 5 of you just take dragon, you live to fight a baron buffed team instead of outright losing the 4v5.
