Heroes of the Storm has changed to Solo/Duo queue
Let me put this in bold:
The game you stole this god-forsaken shit-storm of a queue from has abandoned this style of queue in ranked. After you ripped off their queue style, they went out back to the dumpster you tossed solo-queue into and fucking recovered it and used it instead.
Try copying them again and switching this asinine queue back to normal. For fuck's sake. If the people who started it aren't even going to commit to it, why the hell would you?
