So. There's an issue with the Mantis Blades kill animation. Now, with a Katana, the kill animation is you slicing the other guy's head off, after which you can then move on swiftly to the next target. With Mantis Blades however, it's a slow animation, where you run someone through with your blades, lift the guy up over your head, and then toss him away. On any higher difficulty, any enemies surrounding you will have killed you off, before the animation has even finished. On top of this, when the animation is over, you then have to work on getting your bearings again, locating enemies and figuring out where you are, basically, as the animation interrupts the entire flow of combat. So, that kill animation basically has to be ditched, and replaced with one or several new kill animations, which doesn't interrupt combat, and let's you move on to the next target immediately. Because right now, what was supposed to be the best melee weapon in the game, just doesn't work due to that kill animation :/
