Blade Barrier is annoying

I'm not sure if this is intended or not, but when Blade Barrier activates, my character shouts. Then she proceeds to shout instead of swing her sword for every attack I do while BB is active, so that I am apparently killing my opponents with the power of my voice.

Please take the shout spam out of Blade Barrier, it really doesn't need an animation, it's as close to passive as anything can be without actually being passive, and I'd like to see myself swinging my sword for attacks again. Am I the only one who feels this way?
