how ? it would be the same as racing with one car, like non-subscribers do but instead you have two cars
I don't think he means 2 cars, but 2 leagues.
How would design work when you have 2 leagues operating to different time scales? You might have one league running twice a week and another running every day. At what point do you swap to 'next seasons' designs, and would that either help or hinder you?
The way the games setup its just not pheasable to run one team in many leagues.
If you want to race more you can always race in a league that runs every day.
