Don't maximize RAF just to max it. If you feel that you would like multiple teams of toons, then by all means, level those teams to 60 first, then focus on your main team until you get tired of that one. I have a lot of teams, and it's gonna take a while to get em all leveled, but I have fun playing all the time, so it's not a chore. I'd have to see you get burned out just leveling to 60 cause 70 and 80 are a lot more work.
