Casual players are always glad to get rid of extremely good players
Okay, first of all, this argument is trying to make some poorly-thought correlation between casual players and sucking and hardcore players and being extremely good at the game.
You can be casual and still be extremely good at the game, just as you can be a hardcore player and still suck. To try and say "you're either casual or you're extremely good at the game" is asinine.
Second: Hardly anyone is genuinely that petty. As Jamaree said, casual players are glad to get rid of players who make the game less fun. Skill does not ever factor into someone's decision of "do I wanna report this guy...?"
And the extremely good players.. tend to take the game to the EXTREME
Extreme meaning, they get very ticked off when someone else isn't "trying" or let them down.
And these statements would have been a similar faux pas if you hadn't said "tend to". Even still, I doubt players of high skill are so extreme about being good that they expect all their teammates to be godlike. If they're so good at the game, then they should know full-well what they can do to win the game, and not be even remotely drawn to being pissed off at their teammates.
Think of S1mple from CSGO, is he toxic? Yes, but does he try his absolute best? Yes.
Dunno who S1mple is, doesn't matter. He's just one person. Not a good example.
You will see this every game. 20 kills to 0, go straight to /all chat and blame another teammate.
I seldom see teammates devolve into blaming each other, and when they do, it's often one toxic player trying to get on someone's case for losing lane.
And when players are feeding they'll do something else to entertain themselves.. trolling.
Again; just because you may seem to see it a lot, doesn't mean everyone else sees it. I for one am more likely to encounter a real life unicorn than run into trolls. When players are doing poorly, they don't just randomly decide "y'know what, I'm gonna troll" - they keep playing. They may still make similar mistakes, but very rarely do they troll.
Spamming surrender is a big example, sitting in the summoner pool, trying to convince the OTHER team to report you.
......How is spamming surrender vote - something that can only be seen on your own team, supposed to convince the enemy team to report you?
This kind of piggy-backs from the previous point, but is very very true.
There are threads everywhere (this board and reddit) players seem to think they're "making a difference" by playing the game.
Playing the game to. . get rid of other players permanently, rather than playing to enjoy the game itself.
Yes, there are some people who take unnecessary pride in getting players punished. But, by and large, the majority of the community feels good about players getting reported/punished because that player genuinely made the game less fun for them. They're cleaning up the community, so they're entitled to at least some modicum of pride.
If you can prove that the majority of the community just exult from punishing players for no other reason than "haha, I got this guy punished", I would very much like to see it.
Troll picks, getting enough LP to lose, deranking on purpose
Now every game is the same cycle...
Play, win, rage, report, repeat.
Play, lose, rage, report, quit the game.
Again, you're saying this as though it involves the whole of the community, when in reality, it's only a small handful of players who do this kinda shit.
