Friendship is an overused theme for JRPGs because if you think about it, a bunch of people fighting for one cause that hate each other is either really dark to the point of being emo, or it takes that darkness a shade further and becomes comedic. If you want a serious yet optimistic tale, you need the power of friendship card to be played at least once if not as a constant theme.
Thing is, the system of JRPGs, which is so dependent on developing all characters, requires it to come up constantly. After all, psychologically speaking, the way a person (or character) defines themselves is often seen in reflection from other people. If you make everyone disconnected and unwilling to talk to each other, it screws with the narrative structure of books, it can only get worse for games, which tend to have pretty horrible writing standards as it is. That, or you get a bunch of endless inner monologues, which frankly is not very interesting at all.
Sure you could have a group of badasses together who don't care if they're friends or not. But I can't see that as anything more than a superficial macho dream with no real base in reality or an understanding of deeper motivations for characters. And if a JRPG doesn't do character development properly, then it (often) has NO good qualities. At all. So while that approach might work for, say, a shooter, it won't ever work there.
So in a way, except for the occasional dark fantasy style or comedy JRPG, we are stuck with the power of friendship theme. Reducing it is possible, but it's always going to be a core factor in the equation.

I really cannot overstate how funny that line was. Partly due to the Jackson avatar. Kudos to you, sir.
