I'm just replaying this game the second time through, since I wanted to see if I can get the true ending, and I just noticed there's a damn jump in difficulty when it comes to the first boss battle with Chronos.
Seriously, there's just no reason for why they have a difficulty spike like this so soon. I was at level 19-20, hadn't upgraded any armour because I didn't feel any need to. Nothing in the game was giving me any trouble by this point. Then I get to this boss battle and just remembered that yeah... I'm not meant to just let myself be killed here.
I don't know who thought it was a good idea to give you a boss battle that early in the game, who has an arte that allows them to have control of half of your characters, just to make them kill each other off. That's the sort of shit I'm expecting at the end of the game. Not the 6th hour in.
