Does the ranking system understand leavers?

Just had another two games this evening, both matches I had a leaver on my team part way into the game.

Still a very frequent occurrence clearly, in the end on the second game there was just of us trying to win the match.

Unsure why Blizzard can’t bring in solutions to make competitive fun, and real.
Having unmatched teams affected stats isn’t healthy.
Games should be void from affecting people ranks/stats, and leavers should be punished.

You are absolutely right mate. This guy is a liar and a troll on these forums.
