Its Meat Grinder Content:
Not extremely job specific for success like delve, so frontline DD can vary widely and a group can achieve success:
Instant and high quantity individual rewards:
No fighting over drops:
Always a chance to receive an improved item with the aug system:
Rewards allow you to differentiate your character from the mass of similar job characters:
User Controlled Level Of Difficulty:
Relevant rewards:
Increased amount of rewards based on difficulty:
NM moves can be mitigated to some degree with the right backline jobs:

Whats not to like?
For the first time in a long time Black mage (and certain other backline jobs) can be needed more than a mnk or sam.
I even took a pup on a run, so all jobs are relevant in this content.
Meh -- We need more of this!!
