What happens if a lot of people retire and recreate when the switch happens? (Quite few might call it a day and start fresh in the new sim) Can the junior teams handle large group of active players joining up at once? What happens to the young players already in juniors?

In Football Managers you can usually find tactics that just work better than others, they take advantage of the game mechanics etc and in result you can do well with a team that is not perhaps expected to do so - is there potential for similar stuff in FHM? Some tactical combination brings you the results and there is not much the other team can do?

Those GM´s and coaches who play the game obviously have advantage early on, but could be equally game breaking if fairly soon after moving to FHM every single team plays with the same tactical ideas. Aggressive hockey with active forechecking for example = build towards playing that = every player start to look the same.
