Best way to get Global fast?

A guy named WarOwl did a youtube video on the ranking system but the jist of it was MVP stars count for alot and so does being consistent, apparently playing a couple of games every day or two is better for your rank than playing 10 games once a week. obviously winning against a team of a higher rank will get you up faster so playing with friends that are a lower rank means that you'd have a hard time ranking up quickly
