Apparently this is a fucking thing
And as a result of it, just getting INTO a game takes far longer than actually playing one.
People are jumping into the queue just to autododge at the absolute last second, or disconnect before the game loads up and force the team to do a remake, which takes even longer to just get into a game.
There's a sub-community in this community full of sub-sub-sub-humans who are actively trying to destroy League of Legends in order to force whatever will succeed League to come sooner with the mindset that it will be better by default. Of course, because they barely possess the sapience to learn how to hack and sabotage the servers directly, this is their strategy. Gum up the fucking game by preventing anyone from actually getting into a game.
The community is long overdue for a merciless purge, Riot.
