I agree. Below is my post in the main thread.
I'm going to argue that the new changes are actually really good for a subset of customers which includes me so of course I am happy. I'm a Diamond medallion who mostly credits partner long haul business class flights to Delta. MQDs have never been an issue and 35k won't be an issue. However, now the amount of competition for upgrades/better service is going to greatly be reduced let alone the platinums and golds in the SkyPriority lane. Almost nobody is going to get status through a credit card ($120k for gold, $180k for platinum, and $350k for Diamond) meaning again less "elites" with 25k of spend and 4 segments. The credit card access policies are a non issue as my Amex Platinum gets well over $75k in spend but the lounges are about to get way emptier. The only sad thing as a partner airline earner is the Million Miler changes but I will take that for the other benefits and I am excited for these new choice benefits. Diamond might be the new 360!
I'll add that my domestic trips are mostly reward "free" MC fares that I hope get upgraded to first class so decreasing the competition for these seats makes me happy.
