Okay so this is how I would improve the Devil Breaker system without on the fly switching or the very least make it far more bearable.
1. We can change the cycle anytime via the menu. To make the process quick we press down (or any button) on the Dpad to enter a quick menu where we can arrange the DB in any order rather only be able to determine the order at Nico's van (granted this mean players would be entering the menu mid battle more frequently) OR.......
2. At Nico's van once we make that order that is the set order at all time so say you have a set of Gerbera, Overture, Gerbera, Buster Arm whenever you pick up a new DB it slots back into that order never changing that cycle. However this brings about the issue of how pick ups will work like if you have 1 DB say Overture and you already have an Overture will you be allowed to pick up another.
3. Increase the number of slots beyond 4 like say 6 or 8 via upgrades. I mean if we can't switch between might as well as go above 4 (which would've been perfect for D-pad switching or at the very least 1 button cycling). Nero has a big jacket he could hold more than 3.
4. An upgrade that allows us to use BreakAge moves more than once before breaking.
