Elementz, I really appreciate what you're doing. Not all top players reach out to the general audience like this, we all know that top Elo isn't the worst scenario in the game and most top players just ignore what happens down below.
I must tell you, though, that what you're saying won't change anything. I am 25 years old and I am already doing my best to be a positive asset. I have never played a competitive game before League and during my almost 2 years experience with League I have turned from a very shy and polite person to a hard boiled rager who needs to go out of his way to keep his tongue at bay. Even when I talk on the forums I tend to be rather bitter, snide and kind of a ******bag, which is something I don't really recognize myself into.
But I have to say it's just a defensive mechanism. The people in this community can turn everyone. Literally everyone, into a rabid rager. They go out of their way, sometimes, to ruin your experience of a competitive game. Riot doesn't seem to care to put a divide between normal (casual) play and ranked (competitive) play. If you complain about someone's troll pick you end up getting banned for negative attitude.
I think this all started with the badges thing. It's funny how people react to my posts here or straight up trash talk because they look up my profile and they see I'm a level 6 smurf on US even though it's obvious I know what I'm talking about. Everyone is 100% focused on getting their ego shoved deep into the game, every little kid with parent issues is vomiting all his lack of self-confidence into this game. So this is not a game anymore and you're trying to restore something that's being swallowed by the cancer of anonymous users.
TL DR: That's the internet for you.
Most trolls feel entitled to trollpick and annoy the competitive players in their team, as there's a system that backs them up. In theory, the Tribunal works. The problem is that it's not working the right way.
League as of now is a casual game (if it can be called a game at all, as I said). There's nothing competitive left in it because competitive players are punished for being competitive. It's just a giant chatroom where people happen to play a MOBA game, but that's a secondary activity. The spotlight is all on anonymously venting one's frustration on other people.
Riot doesn't care, so yeah.
What would you do? I quit the game btw. I just don't give a **** anymore, and I'm pretty sure a lot of people will drop the challenge because there's no challenge. When noone takes the game as such, there's no game left to play.
