For me, this was definitely a notable improvement over the 2.3 version. In hindsight, that one felt a bit meh and forced auto-mode wasn't great imo, but here, I definitely like the improvement from before! You can actually battle manually if you wanted, however they reward you more for auto battle which imo is a shame, but I guess higher rewards for a win you can't control once the battle starts...I suppose there is a balance there? Still, would have loved to do the manual one without feeling like it gets me less rewards, but oh well!
I also like those Heartfelt Synergy boosts with buffs and Euphoria and stuff like that. I also don't regret picking Windsong quickly, because how could I not when I love everything about her! She was also part of that Extra Action Synergy which . I also had to take some of the new stuff in at the beginning, but it was nice to learn a bit!
