I want to shoot at the bad guys. The more bad guys there are, the more I have to shoot at. No, I will not stop the inevitable, and I will get killed...a lot..., but the planes, tanks and wirbles are free and unlimited. Its also a great time to play spoiler and kill goons, sneak supps in, hide in the map room, drop their VH just when you think they are about to call for troops, etc. A new war starts a minute later if the they roll the map.
When we have way more players, there is less to shoot at, but they get perk rides cheap so its a great chance to kill high value stuff in early war rides.
With lower total players, 10 guys one way or another often makes a big difference. I wish that were different, but it isn't. Time to make lemonade.
