- Each player has like 2 Ace cards, so overall they can be sent only 2 times as the ace. That way you ensure that no team would be able to send the same 1-2 players all the time.
- So if from 21 games, let´s say you get to the ace match in 6 of them, you make sure that at least there is a 3 player rotation. If you get to the Ace match every game, it forbids you from abusing your JD, Flash, Bisu, etc. so it makes you develop your depth. If you get few Ace matches, it probably means you are a deep team, but still you can have your usual starter Ace only twice, so if you get to your 3rd Ace match, you need to use someone else.
It could bring up interesting scenarios, like for example KT facing Samsung, and KT coach thinking: "Do I send Action, because I want to save Stats and Flash(who have been used once already) for later in the proleague in case we end up ACE matching with CJ or Super8?".
Sending Action, who is not bad himself, but not as a safe bet as Flash or even Stats, could still bring the victory home, but I am taking a bigger risk here. So what to do? I could lose this Ace match and lose the game for saving Flash and Stats, but maybe he faces CJ and wins 3-0 and no need for an Ace, so he wasted Flash saving him for an Ace match that never happened, and he probably would've won with Flash as the Ace vs Samsung.
But anyways, the format is already decided so...
