@smurthys I agree that it's against the spirit of the game, and it's likely that there are rules intended to prevent it, but I also suspect that:
(a) A team could easily select their "non-top" players and claim they are resting their best, and initiating the less well-known;
(b) They won't be upset if they lose, and could easily give the appearance of trying their best while not actually doing so.
All I'm doing is looking at the Game Theory aspect, not judging the morality or otherwise.
