I am SO glad that Crawli, Angie, Souta, and Saki are getting changes. These fights in particular are so nuts, especially Saki since you end up having to do mental gymnastics in order to figure out what's going on. ok so there is wonder room and glitch field and seed and UMD uses the... defense stat but its a special move it was just a pain honestly. I know you didn't reveal everything and I put this in my survey as well so I hope it comes up later, the main 2 other fights that need nerfs IMO is the 2 rift gardevoir fights and Hazuki. I am curious as to how Crawli's fight will work, since reading up on Swamp field it doesn't provide any real buffs to the pokemon or moves he uses. And without rain I almost wonder if it will end up being TOO easy, but we'll see. Bug types are fickle and easily fall from OP to easy.
And for what it's worth: I think leaving intense to the community is the right descion. Have a balanced gameplay expierence and for the hardcore people, leave that to the community. That's how it works for desolation and reborn afaik, and they have better "balancing" than rejuv, even though I would say that the other parts of rejuv are better. The intense community is big, I'm sure they'll figure out how to make things to the general liking of their community.
Zumi mentioned it is V13.5 for these changes, and passwords will be either V13.5 or V14.
