Been looking for another JRPG with parry mechanics. How are the enemy animations and tells? Fun to learn or sloppy?

I saw the timing assist setting and decide to turn it on as I have pretty terrible reaction time to be honest. It did seem to give a bigger window to my dodges/parries, but it seems like the timing for attacks stay the same. Is this intentional? The attack I'm referencing is the Sulimans sH 2000, I'm late/early 90% of the time regardless of timing assistance setting....

I realy love this game, but when i get to first cincert it kick me realy bad, becouse i feel like i ruin people concert. As much as i love music i totaly don't have a thing for it. I don't have ear for music, i don't have a voice to sing and most of all i don't have sense of rhytme. And becouse of this i feel like a real ♥♥♥♥♥♥♥ when i don't press the button in time and part of a music stop playing. I feel like i ruined concert for all of audience who listened to it....

Are the changes significant between the four classes, or just really small flavor stuff?

For a game featuring themes of music this heavily does the sound track hold up?
