I honestly wish 50% of the players in this game, that I have ever played with, were perm-banned.
While I get that it's a frustrating game, and Riot claims "the majority of players are sportsmanlike", I simply do not see it. I haven't gone one single day playing this game without seeing verbal abuse, harassment, and game play designed to intentionally upset another player. Personally, the negative attitude in this game is contagious and spreads like wildfire. It's even visible as far as famous streamers in this game.
I tuned in on a stream the other day just to see what's going on, and the first thing I see is a player intentionally not helping his teammate when he's in a position to. He comes back to lane, purposely lets his teammate die (then dances on his teammates dead body), then proceeds to kill the two enemies. This is while he talks about how he didn't like how the other player was doing earlier. Seriously, this piss poor attitude is everywhere in this game, like an epidemic.
There is nothing but negative attitudes and behavior EVERYWHERE in EVERYTHING related to this game. Complaints about items, champions, balance, other players, EVERYTHING. It's excessive and seriously way out of hand. I'm almost starting to believe that players should get banned on first offenses for everything, including on the boards for non-constructive posts related to balance.
Being away from League for a few weeks helped me see that the balance in the game is fine overall, the real problem is the players and the community for this game. The players who are contributing and promoting this negative behavior are at fault for making this game less fun for the rest of us, and they need removed. The cancer needs taken out of this game.
Seriously, I'd have to guess that 50% of the total players in this game (or more) are not the beautiful butterflies Riot wants us to think they are. They're wolves dressed like sheep, similar to that streamer who technically "isn't breaking the rules" but is promoting this poor attitude and behavior that should not be allowed to continue.
The behavior standards for League need to get much stricter, and this many years in players shouldn't even be given a chance anymore. The cancer needs removed, players should just get perma banned on first offenses, for the sanity of the rest of us.
