It is infinitely better to have 1 good team than 5 average teams. As a starter, you should have your second team as Osh team; will pay off in the long run big time. You waste to much resources on spreading around your heroes. For the start, you can’t go wrong with popular heroes/teams. Just my 2 cents. Have fun while you’re at it!
