There are only so many ghosts, so, only so many players If there's more players than ghosts We should use competitive play to determine the "top 100" sort of situation, only on a much larger scale, everyone qualifying earns the privilege of being considered one of the canonical guardians each character mentions from time to time We could also do a similar thing in PvE to determine those left out as the canonical guardians that are "studying" the darkness through usage of it I for one think the community could do this ourselves if Bungie liked the idea
