Another reason I didn't like 2 is that it felt like almost nothing had any... weight? Or consequences, I guess is the term I'm looking for. Like, throughout the entire game you're constantly losing most of the time, and yet no one ever dies, nothing of any real significance happens as a result of you losing: Rean's Dad gets injured in an attack and the town is damaged... but then he recovers and the town goes back to normal like nothing happened. You constantly lose against super-powerful foes who just decide to let you go half the time, because... reasons?
It's like everyone in the game treats these big battles and fights as sparring matches. As soon as the fight ends, it turns into "Well, you still fought well, but I had the upper hand in the end! Now, let us all go home and train harder so we can having another sporting match next time, eh?" (okay, I'm exaggerating, but that's the vibe I get a lot of the time).
