How do rankings work for teams that lose in the same round? Will it be by number of cards left in the vault, or overall win-loss record? I think the latter seems to be more sensible.
In the last war it went by number of cards in the vault. It will probably be the same here.
What's the reasoning behind the "number of cards left in the vault" ranking? I don't mean to ask this in a rude manner or anything. To me, it just makes more sense that you'd reward a higher rank to the team that has done better throughout. (And then, if teams are tied for number of wins, the number of cards left could be the tie breaker).
That's not really the ranking we are primarily using. We are using the "during which round you got eliminated on" ranking. If two teams get eliminated during the same round,
then we go to the card thing. And the reason we use cards instead of win-loss ratio, is that the latter doesn't take your penalties into consideration.
Think of cards as your army. After the war, nobody cares who won some individual battles. All that people care is who is left standing. What you suggest makes also sense, but it's more of a "sport" approach to this.
