Wanderers Minuet doesn't fit the BRD kit.
Unlike MCH that has been designed from the ground up with Gauss Barrel fitting the kit (where you can insta cast the barrel under rapid fire and the skills can be insta cast with procs with you can activate with ammo).

WM is just a skill slapped on top of a class that has a ton of OGCD's including refreshing ones that has no guaranteed movement giving abilities that come with WM like the BLM/MCH have and is basically an afterthought in an attempt to balance BRD/MCH which has horribly gone wrong.
