One of my favourite executions, but practically absence of blood on the enemy's back side where she stabs, makes it look very bad, as if she were to chop someone's head off, but the head didn't fall off. Usually, blood covers lack of details, like absence of stub wounds or cuts, but during Wicked Rampage, there is basically no blood where she stubs. It's like she's stabbing an empty space.
P.S. yeah yeah, there are other things to worry about, but common.. A little care for details will go a long way.
