As with the initial announcement, I'm gonna need a bit of time to digest and analyze all of this to determine what is the best value outcome for me pertaining to future flying.

A few brief initial observations/thoughts:
1. The rollbacks/adjustments are far broader than I ever expected. Certainly it's still harder to earn status, no MQD waiver, limited sky club visits for card, etc. The program is still changing greatly. Nonetheless, I expected some limited "here have a candy or two" gimmes from DL, not revision of multiple aspects of the new program.
2. In a world of limited club access, the change to measuring sky club allocations by 'days' instead of 'visits' makes much, much more sense.
3. Never expected MM changes in this (I'm not MM on DL anyway, but that whole section of the announcement was a surprise)
4. UA already gave Gold for 1MM. DL now gives Gold for 1MM. Hoping this pushes AA to give Platinum (their equivalent tier) instead of Gold (their DL Silver equivalent tier) for 1MM.
5. Clearly, these changes were met with a broad negative reaction, beyond just folks like us chatting on a message board. The breadth of the backstepping speaks to that. DL really messed this one up and they realize it.
