Why does every game for me have to end with having to report somebody?

And no, before reading ahead, no this is not about reports for simple trolling, low skill level, or "highly presumed and completely subjectively accurate" accusations of intentional feeding, this is something that's more about having aggrovating or disruptive behavior in your chat.

So over the past games, my MMR (or at least, the skill level of players I'm being paired at) is skyrocketing, I'm suddenly facing players in high Silver to mid Gold, and holy heck this environment is extremely hostile. Almost every game, I get people being completely disruptive by trashtalking non-stop in /all chat, trying to aggrovate/tilt someone on purpose, constant flaming on the least performing player in the team, constant nagging on little details.

Last game; "Why do you even lock in Veigar if I don't even see a ward of yours?" Says a Warwick with 25 vision score says against a Veigar support with 36 vision score. Oh, and this Veigar Support was 8/5/0 (of which no kill was KS'd, the adc just kept being overextending and kept dying.) and warwick was 2/6/0 whilst "camping" top. People aren't even in the position to complain about others, and then they flame against the player that's performing the best in their team according to their role.

This kind of behavior ethic I've stumbled into is just so annoying to see. For once I had hoped that growing from Bronze 1 through silver into gold was going to be better. Boy, am I wrong... Time to put /mute all on my Ctrl-V again.
