Another thing would be to ask the question "If a team is only committed to playing 1 duel, why aren't they eliminated when they lose that duel?"
That is actually a pretty good question, I'd say. Sounds logical enough.
Heh, last war, every team below 300 cards was under a risk of being eliminated.
I will ask this then:
If a team is only committed to playing 2 duels, why aren't they eliminated when they lose those duels? (90 cards)
If a team is only committed to playing 3 duels, why aren't they eliminated when they lose those duels? (120 cards)
...
If a team is only committed to playing 8 duels, why aren't they eliminated when they lose those duels? (288 cards)
The rules create those gaps, fixing one gap when there are plenty is weird.
