So you're saying there's some bug that allows you to get territories faster when you kick people out of gang?
I just had a glance over the source and there appears to be no way for this to happen, the score is calculated by:
(Kills in Zone - Deaths in Zone) + Players in ZoneAs you can see, it's not dependent on having less players. You're actually better off to have more players who are inside the gang zone. If someone does know of an exploit then I'd prefer you to send me a PM so it can be fixed.
It looks like it was a good turnout. Was the playercount peak at 61 or did it get higher?
