Yeah I expect that balancing the two groups was their main intent. Though it also seems that just fusion was their main concept for this game (much like visions were for XC1); be it of cultures, of arts, of people, fusion is everywhere. Based on the now discredited 4chan leak, it was thought that fusion arts leveled up the interlink levels iirc; that'd be a cool way to encourage engagement with this system.
P.S. Fun is totally allowed (and it isn't my place to say whether it is or not since this isn't my thread). I just really like to avoid those terse, media-based reaction responses because its hard for me to read intent in them (I'm just really bad at reading social cues in general). In the past, I've almost always read them as more snarky and mean-spirited than they were intended, and its lead to me alienating a few potential friends and derailing conversations. Posts like the one I'm quoting or, to provide an example from my own post history,
this one, are much easier for me because they provide something more substantive for me to latch on and read into (Its helps me understand what the person is really trying to say). Its give me something to structure my response around that doesn't involve abstractly (and often poorly) guessing what someone meant. If I came off too rough in my initial response I'd like to apologize. I've just been frustrated by them in the past and it drew those emotions out again when I saw your first response.
