You know, if you stop giving up instantly once you see something you don't like you can actually
learn something and even have fun.
Just saying. There is always something you can try doing even against most notorious and broken killer setups (Like spirit with best addons, mori and stridor). Even if you don't make it out alive, you can still get some points or train different tactics like stealth. You can even learn or train different tricks and jukes against killers you dislike.
But if you just perform hook suicide, DC or lead killer to teammates in order to finish the match quickly, you'll never learn anything. You will never learn, get any points and you will just end up being another loser, who gives up instantly once seeing something harder than you expected.
I'm mostly talking to survivors, since they are the once who quit/throw more often than killers, though this goes to killers in some way. Even if you won't win, you still can learn and practice that time, when you get "these" survivors. Just don't quit because you decided that's too difficult for you. There is always something you can get even out of worst situations. Get a chance to practice your power on huntress or some other skillcap killer, get better at looping and mindgaming or simply get as much points as you can.
As for you, people who trashtalk in chat and BM because you are winning and your opponent is just trying to play the game even though he is not doing well. Nobody loves you. Deep down inside you know that, but never admit even to yourself. Get some help. Get this poison out of yourself and stop spitting acid on other people in a desperate attempt of trying to raise up your self confidence because you feel safety behind internet anonymity and just end up ruining everybody's day and enjoyment in this already pretty frustrating game. Just know you are awful, but you still have a chance for redemption.
