I think this is a dangerous move. There are dedicated archers that play this game. As often as I get headshot or filled with 8 arrows, I still feel as if we should show a lil respect to all the classes and not kick the dedicated archers and cav right in the balls just because a few melee don't wanna fight them. We already have flags that guarantee a closer distance or loss. If a melee player hasnt left by the time there is 20 or less people, they're not gonna leave just because theres a couple archers. The archers however will be guaranteed to leave when there is 20 or less players which is fairly early most nights.
Pros: Maybe getting more people to stay longer during 10-20 pop.
Cons: Guaranteeing archers and cav will leave when pop drops below 20.
This may be safer and I would feel more comfortable about it if the number decided upon was 10 pop rather than 20.
