This is a good initiative and an initial WP minimum is a way to go.

I'd say we have to watch out for the proto-stomp effect. I have had matches (mostly skirmish), where all points are captured very early on (within the 1st minute), and then they are held by the opposing team until the end. In this scenario, after the initial slaughter, most people hang back, take some potshots , but don't really gather many war points as they are all redlined. They may try to do so (I always try as I'm a lone wolf) , and in doing so, lose even more suits but don't necessarily rack up WP. It would be delicate to punish these people who are in fact trying, but not necessarily earning WP, and are actively losing suits. What would then happen is if people figure out how the system works, once they realise there is no hope of a minimum WP, they will simply leave the game , as hanging around doesn't benefit them, and this wouldn't improve the game for anyone. Even a proto-stomper would like to play against other people I'm sure... and if they aren't killing people they aren't getting their minimum either.

Min WP threshold should be equated based off median team score which would allow it to more accurately respond to varying battle scenarios.

Perhaps even a combination of mean and median calculations, perhaps preferencing the lower of the two.
