To everyone who says ranked is a game of chance...fun fact!
In 100% of every match played always, 50% of all parties involved lose the match.
I understand it is frustrating, and that matchmaking and the ranked experience as a whole arn't perfect but it still comes down to the team that plays best wins more often then not.
And unfortunately, part of "playing best" also includes doing a little morale management of your team, being a good teammate, a good leader and in general just not a jerk.
Trust me, I wish there was more luck involved, maybe then I would get LUCKY and hit gold!
But alas, I'm kinda just bad....
