Class changing, are we unique?

[PArcher]

If we're going unique, many NPCs are more unique than us such as this one knight of Heaven's Wards

To be fair, many of our job abilities are unique to us (whether we started their use or rediscovered them); Blood of the Dragon and its abilities are entirely new, for example (actually, I think Battle Litany is as well), and right now we're the only one who can use the Dreadwyrm Trance. Scholar abilities are also our own for now, we're the only one able to channel tier IV black magic, and so on.
