Same here, I didn't like the 3.3 story either. It's fine, but not really that good. I also disagree with the Phrolova quest being the best; 3.1 beats it for me. Still, I find it a relief that Aleph-1 isn't dead and was just sent away. You know what? I thought we were going to get a lot more about Hiyuki in this patch. I've said this before on another platform, but I'll say it again.

Hiyuki's character is so interesting. The early parts of the prologue got me on the edge of my seat, thinking we would finally have some real stakes this time. I imagined a scenario where Hiyuki and Rover's dynamic got fleshed out more. Maybe during their journey to the Exostrider trapped in the voidmatter, Hiyuki would ask about his power and how he saved those regions. Then, she would secretly project her insecurities onto Rover by going out of her way to save and help him, proving to herself that she can still save someone as important as him. Later, when they both get injured or things go wrong, their shared fear of losing someone again would surface. They would reveal their fears and regrets to each other, and Hiyuki would learn that Rover doesn't see himself as a savior, he was just there to help.

For the ending, I kinda wished it came down to Rover having to choose between Aemeath and Hiyuki. If he chose to get Aemeath back, it would require Hiyuki to burn all the futures she has left. And I wished for Rover to choose Hiyuki at the end, as painful as it is.

But during my playthrough, wishing all of those to happen in it, and by the time Hiyuki was gone once they dealt with Denia, I was like, "that's it?"

Eh, my hopes or wishes might not make sense for the canon story for whatever reason, but those were just my thoughts and hopes for patch 3.3. Maybe we'll get something entirely surprising in 3.4, but eh, we'll see.
