This thread is far too long, so I haven't been able to read it all. However, I dont know if anyone has noticed the new kind of trolling. These are the guys that jump into champion select with some rather toxic attitudes which include, but are not limited to:
1) "I'm going top, I don't care what anyone says, otherwise I troll."
2) "Riot doesn't keep champion select logs so I can say whatever I want in here you ***** ***** ****.
3) "This is my smurf account, so I'm playing [X] champ as mid/carry/top etc, no matter what anyone else picks"
And so on...
During game, they don't say much... I had one that didn't like me at all during champion select. He had caused a previous person to dodge queue due to one of the reasons above, and I got in his team again, so I told the team that he was fairly uncooperative. He proceeded to take top, but then would take my jungle throughout the game. He tried to instigate a fight during game by saying I sucked and so on, but I just didn't answer.
We eventually won, but I did not feel like playing a game afterward.
When I checked his profile, I saw that he actually receives honor, in spite of being a jerk during champion select.
Oh well, can't sift them all, I guess...
edit: Awesome, I just got into a game exactly like the one described above... I knew I shoulda gone to bed... Ugh.
