Before "DRK was in world first" argument.
Remember DRK was also in UCOB world first (for a different reason), SMN was in multiple world first.

If DRK was chosen, it's not because of Unmend, not because of TBN, not because of Esteem, not because of Living Dead.
It was simply because it had bigger damage. If any other job had bigger damage, they would've been chosen instead.
Design of the job remains terrible.

The fact that most world first are BRD proves this as well...
