LMP/GMP decrease barrage attack speed? Bug?

I originally assumed linking those two supports would cause you to fire more projectiles in the same amount of time as the barrage, but it looks like it just fires more at the same speed, making the channel longer and feel clunkier.

Is this a bug?

I'm pretty sure you're just imagining it. I used to use GMP Barrage and the animation definitely gets faster as you increase your attack speed.

Adding extra projectiles to barrage will make it take longer than your attack time, as each one takes time to fire.
