Is there any documentation for digivolutions at all? I've looked everywhere, and I like some sort of control over what I get usually. And is there Exp. Share Gen 6-style? I want to play through the game for sure, but I don't have a lot of time so I'd definitely like to reduce grinding. I've also found myself very confused by the Battle UI, design-wise, it's a little hard to look at and know where the cursor is.
