What has made Chaotic Raids launch more successful than Critierion so far?

The fact that I can still reasonably get a PF filled with 24 slots over a week and a half in is so nice. Especially compared to Criterion 4 man where I wasn't able to get any parties after a week. What can Criterion raids take from Chaotic in order to increase their longevity even slightly?

As a side discussion, the fact that all the rewards for Chaotic amount to 730 gear, a hairstyle, ans two mounts made me realize how at odds XIV balance/systems are with creating more appealing loot. There's not many options beyond just offering BiS gear bc armor/weapon bonuses add a whole new layer to the balance discussion. Can't have too many layers to balance discussion bc the team already adapts to balance slowly. Also can't have too many layers to balancing bc due to the main content being made around 8 people, an individual job's flaws or boons matter way more (less people = more responsibility). But there also should be something more than just cosmetic...
