Impractical

The item unlock system is very player unfriendly. To unlock a certain item you must get specific ranks. An item that requires a c rank cannot be obtained with rank b or higher. This is not practical as it forces the player to dumb down their playthrough for these items.

In addition, the new expansion of the devil trigger; while fun, is very limited as it cannot be used freely in combat to switch in and out of it.
