Definitely need to copy current settings to new team. I have invested close to 15 hours just in setting up roster, game planning and formations. After each set I run 5 test games against the same team. I am a little concerned at the wide fluctuations in what would seemingly be the same variables. I have found that I typically have 3-2 advantage in those 5 test games but scores go from a 10-2 loss to a 22-21 win to a 30-3 loss to a 31-10 win. I say this only to say that it is hard to know if my settings are sounds due to the wide fluctuations in results. I know it is a Beta so it is just a statement of fact rather than a complaint.
With that said, I did want to echo the extensive set up and while I agree that once you get it set it should be easy but as I look at the long term picture against savvy owners, the daily changes to game planning would require a bunch of daily adjustments. Being an owner of only one team in one world it isn't as daunting as it may be for others but I have to wonder if 40/60, 50/50, or 60/40 has enough points of data to make it worth the pinkie tabbing rather than choosing a "balanced" drop down.
