I would love to see this.

25 people - 100,000 kills total for a hat.
it only count kills in the towers with tag on.
if they kick the person, it minus their total.
if they recruit the person, they start with 0.

prevents:
-abusive leaders that log in every 10 hour
-AFKers, who doesn't contribute much.
-friends gets free hat.

only downside is, what's the point of having a flag/tower?
