My comment was in general, not just for this game, and don't worry, each one has his own way to see difficulty.
Well in practice by test playing a little what I have made, making the game less grindy by increasing the exp and money also made the game to feel quite a bit less challenging, that's why I also beefed up the enemies a percentage of their oiginal stats.
About buffing the player... Hmmm I made characters better, (For example Jean and Sten got some big improvements so people may want to use them now, and I also gave Ryu some offensive spells just because I get a kick out of it, lol), but I didn't go too far, or at least as stat numbers go it doesn't seem so (I'll have to see as I testplay).
I also made some changes to the shamans so they change the character instead of just "improve them" in the case of transformations.
For example, Jean transformation gives him a boost on attack and doubles his not very high speed at the cost of defense and AP. That way I try to make the normal characters feel useful and depending on what you want them to do you may prefeer to stay in a normal form.
Transformed Jean is a faster, more offensive physical warrior, while normal Jean can endure more pain and be a better caster by having more AP to attack or support the team.
I don't know if others will like that, but I for one find it more interesting. "Rebalancing" is another very subjective thing too.
