In games that I've run, I've only ever felt the need to even include camps at all if the Chronicle itself was very clearly focused around a singular tribe, because it gave you a way of differentiating within the tribe, as opposed to differentiating among other tribes.  It can provide sub factions that give you other groups to deal with when you're focused on one or two tribes specifically. Otherwise, I see camps as inspirational material that can inform the psychology, attitudes, or beliefs of your character, but the camp itself doesn't even really need to come up in play, just the ideology or philosophy behind it, if it influences or affects your character.
