So there seems to be some conflicting info on why Guardians are special. On the one hand, they're "able to wield some of the Traveler's immense power". On the other hand, the new info we've gotten makes Guardians seem less like the Chosen Ones and more like People Who Are Good At Things. Warlocks have some connection to the Traveler, as they have studied it enough to master some of its "arcane energies". Titans are descendants of heroes, and they protect the Last City and its inhabitants. Hunters are outlaws, who are unique because of their "daring and ingenuity". These are all impressive things, but none of them imply a connection to the Traveler. Explains plz.
