Boss Rush Mode

[Brother Thaddäus]

I was experimenting with some of the Pictos and Skills on my party and found myself trivializing a big chunk of Act 3 bosses.
Would it be possible to add an additional mode to the game that allows refighting bosses (outside of NG+?)?

I feel kind of bad for one-shotting Clea after seeing what a cool boss fight it actually is.

I wish they'd open up that inaccessible part of the Endless Tower and put all the endgame bosses in there that were not a part of the main story.

The arena behind the giant door is massive, so could be used precisely for that purpose.

I want boss rush, putting them in their original arenas (So Renoir at manor), alongside their original music, back to back, and I'll play for weeks.

This is going to sound stupid, but you can remove some of your damage-boosting pictos/lumina, excluding Painter Power. People keep talking about doing too much damage and steamrolling content but don't realize they could "nerf" themselves to balance the scales. Aside from that, though, your idea of a boss rush would be pretty cool. Granted, Endless Tower acts like that in a way.
