Hello! I was told I should post suggestions here?
So, as we generally know, Munitions Mastery's animations are kinda buggered, especially if your character is already using other weapons (such as Dual Pistols). This is a difficult problem to fix, as it's an issue stemming from how the game handles animating objects entirely.
So, how about a simple fix that would make everyone happy? Add pre-existing animations as alternate animations. For instance, [Sleep Grenade] could have an alternate animation where the grenade is fired from the arm, and/or an animation where the grenade is fired from a generic grenade launcher.
I don't entirely know what adding an alternate animation entails, but perhaps it's easier if no new animation is actually necessary? And it'd make a huge difference in making Munitions Mastery useable.
I for one am eagerly awaiting some kind of fix for Munition Mastery's animations!
