I read a lot about TL2 PD's problems, and while I agree with many of the points raised, I have a... slightly different perspective on them.
First of all, the stats "degeneration". As somebody who defeated WINNER 255 times in TL1, I honestly saw it coming a long while ago. I mean, if you are complaining about "fast ticking ATB" and "unreadably big damage numbers", check this out:

As for the lack of strategy, well... that's a problem with TL2
as a whole. It's definitely not just the postgame. Sure, some bosses were harder than others, but ultimately, the number of bosses in TL2 which required a complex strategy is incredibly small - most of them are just about smashing through with the right element, often with piercing attacks. While TL2 has a lot more complexity when it comes to team choices, TL1's fights were much more technical. Heck, everytime I compare a TL2 fight with its "equivalent" in TL1, I sorta feel underwhelmed. TL1 Alice vs TL2 Alice, TL1 Yukari vs TL2 Yukari, TL1 Yuyuko vs TL2 Yuyuko, and so on. Even when the fight almost plays the same (like in Yuyuko's case), the overall lack of power and "tricks" in TL1 meant you needed to play much more carefully and be more opportunistic with your damage dealers. Not to mention that most of TL1's "climatic" fights - Alice, Eientei, Yukari, and especially Rinnosuke - were far more complicated to navigate through than nearly any TL2 fight I could think of.
Overall, I do like TL2. And I'm sure that, when
will be a thing in TL2 as well, I'll definitely see it through like I did with TL1. But I don't expect it to be anywhere as "fulfilling" to be honest. TL2 chars are just too strong - they are bulkier, they got more tricks, they do far more damage for their levels - compared to TL1. In short, my blunt suggestion for those who actually want to play complicated and strategic fights... would be to drop TL2 altogether and go back to TL1 :-)
