Here's another question. I know it was previously mentioned that it is advised for people to replay through the game once E5 drops because they might miss certain things if they don't. If I was to continue with my current save file and miss out on the things that have been changed prior to the E5 continuation of the story, would the things I'll have missed impact the story later on in the game? Asking because I think I'm in the minority of the player base who actually finished the game like 2 weeks before Caz made his hype return and I put a lot of time into EV training and getting the best natures that I don't really want to start from scratch, but if there's anything super game changing I would be OK with restarting. Sorry if this falls too much under spoiling the rest of the game.

Question for anyone, but can you guys shed some light on which characters got buffed? Apologies if it falls under spoilers.
