It's extremely boring. I've kept up with everything up to this point, but now I'm done. I liked the idea of power creep, but it doesn't really work with seasons. I have to use a bunch of cards I don't want to use to earn/collect a bunch of cards I don't want to use until I finally get to the ones I want a few months later. And then I can't use them when I earn them if I want to progress things in the next season because they don't count towards TA. And you basically have to finish TA to earn the collection boss rewards. The entire framework is terrible. Season 1 should not have ended with 99s, and season 2 should not have started with 89s. That's not "creep", that's a full reset that hardly anyone wants to do.
The XP rewards in programs at the end of season 1 finally rewarded you, but then they nerfed them back to the earlier program levels for the start of season 2. Repeating the same bosses in the program path 3 times is just stupid and lazy, especially when P5ing them gets them to the same overall as the next one (and yes I realize the attributes are different). It just feels like a slog to progress in any meaningful way. I really want the HOF Griffey but I can't put myself through this and have fun with it anymore.
I love baseball and have played every iteration of the show. This is pretty much the breaking point. I don't have any faith they're going to improve this, but I guess we'll see next year.
