One major improvement to the game IMO would be to have the active formations. fixed to your squad players, so that not just the formation is saved but the players and orders for the formation including auto subs.
Step 1, select formation, Step 2, place players, Step3, orders and auto subs. Step 4, select match formation game 1 or 2.
In action it would mean one click and everything on the game board changes to your desired formation.
The reasons I suggest the above:
1. When games are scheduled 15min apart, on occasions the game engine does not give you the squad board back quick enough to make the necessary changes, I have already had this happen once this season and once last season out of two match schedules, in both cases when I eventually got control of the squad the timer was showing, maybe a backup or a server problem, either way I was unable to make changes and I know that others have had similar problems.
2. Not all gamers can make every match, giving an option to select formation 'A' for game one and 'B' for game two or 'C' 'D' would make life a lot easier, it should also eliminate the above problem with the timer.
