All good points. Just a minor thing, but when you say "you fight, you're more likely to lose," I'm not sure if this is true, because for a team to lose, another team has to win. So you could very well aay "you fight, you're more likely to win."
Now, you could make a case of a team that could easily and overwhelmingly beat the second team, and if they fight, they're more likely to lose players, and thereby, they're more likely to lose. Because if they fight, the other team could lose players, so if they fight.... they would win anyway, so the likelihood of winning doesn't increase.
