How many ranked games did you play before you started to progress?

Tip from everyone I know that's in Diamond: Play op champs, and never look back.

Me getting to diamond: "I'M ONLY GONNA PLAY THE CHAMPS I LIKE LIKE ASHE AND CHO"
Me in diamond: "welp time to play another freelo champion because I can't do anything else"
It's pretty much why I stopped playing ranked. :|

You don't need the op champs to get to diamond, but I'm sure it could help, for as much as I hate it. It's stupid and boring and static.
