i have idea and i ll try to explain.
1.Each faction member has 1 "toll credit", this credit is moved from zone to zone with him, latest 6 zone tresspasings are converted to "active credits". Only these 6 "active credits" determines which and at what speed zone is being taken , same as always, except fact its limited to 6 for whole core.
2.If faction travels thru the hostile territory, only the latest 6 tresspasings are recorded, so if you send scout to check adjacent zone for enemies, you ll temporary loose 1 credit from your zone and put it to scouted zone. If scout dies, his "active credit" is given to 7th "toll credit" in order, unless there is not any other gangmate in core, so his "active credit" remains unused.
3.If you enter zone which is being taken by enemies. You put one of your credits into it, reducing their timer speed by 1. If equal numbers of "active credits" from both factions are present in 1 zone, timer is suspended. Timer can be launched again only less than 6 members and inequal number is present in zone. So basicaly dieing or leaving, but just below of 6 players in zone.
Hope its clear, but there is more shady situations which may happens.
