Bozja was damn near perfect.

Large scale dungeon content with normal mode and savage.
Lost action system was more robust.
Duel system.
Queue system for fates.
Could level other jobs while in zone.
Could progress all stages of the relic while in the zone.

Occult Crescent.
No queue system for fates.
No duel system
Phantom jobs seem too limited and safe compared to lost actions.
Cannot level other jobs while in zone.
Cannot complete all relic steps while in the zone.
No normal mode for large scale dungeon content

With this current relic step, Occult Crescent wont have any value for 6+ months. That is crazy
