It's kinda nifty when they're initiating team attacks and end the battle, but really nothing major.
For the syncing issues, you just need to replace one of the file, I had mine on silencing some of the pointer that causes the desync, so it's doing really well.
Only problem with using JP rom as base is that the .sav doesnt match the EU version, so if you wanna use it, you'd have to start from scratch, which I did anyway because I felt like missing a lot of the experience by just silencing pretty much all the fucking sound after the desync occurs on my first playthrough.
That and I missed some milestone sensitive characters...so I ended up just restarting anyway.
And man, this game doesn't even try to be hard...by just spending like 10-20 mins of trading, you'd easily unlock best armor and best/second best gears from the HQ shop, and you can get the quest for the strongest sword by just getting 2 or so characters. The only really annoying part about the battle is that if you're caught against enemies that resists your damage type (read: slash, who the fuck uses anything else?)
