Disclaimer: I'm an NEC rider based out of NYP, but I'm not feeling great about the new AGR so I'm going to share my perspective (if for no other reason than to vent).
I travel most extensively to to BOS. I travel occasionally to PHL and WAS. I get that the "city pairs" were wonky because you could do PVD-BWI and get less than 500 points while someone else traveling just from BOS-STM gets 500, but if the TQPs required for Select Plus and Select Executive stay the same its going to be much harder to earn stays. I qualified for S+ in June and should hit SE in October courtesy of 500 TQPs on my $113 low-bucket tickets to BOs. With the new system I won't come anywhere near spending $10,000 with Amtrak. Based on the current fare structure, I can really only see NYP-WAS travelers qualifying for SE. In fact, if my travel drops slightly next year I may not even qualify for S+. The Club Acela in BOS is about to get even quieter.
Now that it's harder to earn TQPs and points on the Acela (and no 100 point minimum) I wonder if they'll drop the cost of the Club Acela passes and first class upgrades?
I get that I'm not going to get a lot of sympathy from most on this board as a business traveler who has my Acela business fare paid for me, but please know that as an NEC-North customer I'm also feeling like I'm losing something with the "new and improved AGR."
