There is an argument to be made for taking into account the amount of time dedicated to the game. And token farming takes time... Ergo, it is every bit as valuable a use of time as studying counter formations or opponents form/players/strategies.

I think anyone who has reached a level of 20 or above should be considered a top manager. It takes dedication to get that far. T11 will surely have thrown some cr*p at you by that point, so you must really have some commitment.
