Storm's edge is a fun super, but as you can see from the video, it does not work at all on Kell's Grave. Also in my other footage, half of the time that you use the super, you lose out on 1/3 of its damage because one out of the three spin attacks doesn't even work. Bungie please fix this. This is the buggiest super in the game, it's the most recent one from the most recent expansion, so it shouldn't be buggy, needs to be consistent, and probably needs to hit harder than it does.
