Math doesn't add up on Dual-Wield Volcanic Fissure attack speed

Bug Report ID: #3025922981

I've got a slow weapon set with a 2h that takes attack speed reduction nodes.

My fissure was accidentally set to my dual wielding set and felt like a complete slog for no reason.

Dual wielding 1.45 speed weapons with Fissure causes it to take damn near 3 seconds to fire. I can't explain why that would be. 30% less attack speed results in 1.45*0.7=1.015 attacks per second, and it's obviously taking way longer than a second.

It's way the fuck slower than my weapon set 1.
