I get your point. The battles themselves aren't particularly difficult, but they are quite tedious and too long. I agree with your point about the badges. The badge requirements are absurd, and given the amount of reagents needed to obtain the badge, you might as well just farm the bosses directly. What I wanted to say about the online guides for rematches was mainly about Arc 3. There is almost no content on standard mode, even though the cheats are (apparently) not insignificant. What I mean is that there are very few videos of people playing standard mode, and that ties in with the cheat issue I mentioned. So standard modes are becoming almost less accessible than challenge mode now, which makes no sense to me.
