the animation is really cool but is almost 4s long, most skills will cut it complety before it ends. well is basically what current DRK is, a bunch of animations that are cutted by the oGCD "looking at you bloodspiller/soul eater" but it could be cool is the 4 first swings are a GCD and the last swing a oGCD that need to be chained with resolution. the other problem i see is the moon icon that is already present on samurai here but it would be nice if they replace it with edgy dark effects.
