There isn't much to discuss regarding how the skill plays, it's just an aoe dmg finisher, in aoe situation you press this instead of evis, that's all it has, nothing fancy about it. Even if beta isn't in dmg tuning phase it's ridicolous that we have a finisher that deals less dmg than the cp builder.
But if you insist, how about the animation, which is the same as shurriken storm except that the character jumps. I can reproduce it already on live infinitely with spamming shstorm while jumping.. it's boring as hell for me.
