Sorry, gonna burst your bubble here, mate.
As we've seen in gameplay footage and maps, the
only time you would run into and combat other teams is within dark zones. Limiting your "clan" to just dark zones (it sounds like you are attempting to do as such) will be counter-intuitive; for reasons listed below;
It makes sense that only a set amount of teams will enter a dark zone, for server load purposes, and once the limit is reached teams that try to enter that area will just be transferred to another instance of that particular area (on another server).

Limiting yourself to a single dark zone means you miss out on other areas of the map, and the map is going to be huge.
Source Not to mention that given the map size, a high traffic point would, I imagine, have a way around even if it was a dark zone, which it may not.
You would also have to contend with the elements in a dark zone, lets not forget (refer to the recent e3 gameplay footage). Enemy Factions (AI controlled) are also on the prowl. Assuming you would want to camp high level dark zones for the higher level loot, you would be facing higher leveled enemies as well as the "away team" that you intend to extort. (And you're not going to have your 24 members as backup, remember, with the server load in mind)
Assume you camp low level dark zones with high traffic instead, chances that you run into a team with higher level equipment than yours is a likelihood, high traffic after all. In addition, killing low level individuals would just make the word spread, possibly making your team public enemy #1 ?
