[spoiler]The back-step L2 is perfect for invaders and other humanoid enemies. While not having a visceral attack (R2,) while in the dual sword state, they do allow for several attacks that increase in speed if you spam R1. They are very good and have high scaling with skill and arcane. Think of them as magic blades more than regular physical blades. In my opinion, these are what I have been waiting for in my time of playing, and very much what works so well about bloodbornes style of fighting.[/spoiler]
