As far as how it works, I would guess it is like pvp valor (or whatever they call it). The more you do the higher the rank you are and the more gear becomes available. Maybe it has a cap, I dunno, but since you get it from grouping with others I imagine it would take a while to get max since you will be gathering these points through out the entire game (not just a specific level/area like reps in wow).
