It occurred to me that the criticism for freestyle games could be stopped easily without actually making games take any longer. Everybody would have the ability to start their turn whenever during a round as per normal. However only one player could be playing their turn at any one time. This effectively prevents the problems with freestyle such as deploying on territories that are no longer yours and people waiting to attack until half way through another person's turn. This would be especially beneficial to RT games.
Sorry if this has already been suggested, but I think this would really cut out a lot of the problems with the current system. Thoughts?
