Ok; then we'll stop arguing.
If we are on strict maths, nothing is 100% sure unles all variables are taking into account. Perfect LR, fully LR runed team will lose if the player wants to lose, doesn't care, somehow wants to expend more, etc. Nothing NEVER is 100% sure if there are any kind of variable.
That being said, we all are trying to figure a balanced team that assures optimum Crown waste, therebefore, not losing. Thats our 100% we would be looking for
100% hard math is impossible, so yeah, you were right. (But also wrong at the same time, as I do).
