Depending on how long you play each day, I don't believe it will take you very long to hit 60. Most people with RAF hit it after like 2.5 days or so played time. So even if you lvled up 5 teams seperately, that's only 12.5 days played time which you would be surprised at how quickly that can be achieved playing full time lol. 60-70 will be a lot slower though.
