I could see Bullet Barrier getting adjusted in some way, either becoming a 'Deflection' skill that doesn't stack with Blade Barrier (and any other similar skills in the future). Or making it not work in melee range is also a viable option.

If I had to pick one, I'd opt for the former. Too many mechanics already encourage scrambling behind someone and shooting them in the ass, and Desperado Stance isn't nearly powerful enough to warrant nerfing. By giving them classifications, people who run the stance without Blade Barrier won't be on the receiving end of the power reduction.
