I'm aware of the AoE damage, but like others have stated, the hammers have a fairly large blast radius. You could try and block it from 5 feet in front of me and you'll still die. I don't do this myself, I'm just bringing up the fact that the only super that can be blocked is GG. Supers like Arc Blade, GG, GoS, FoH, and Nova bomb are one hit kills when they hit the target. GG is no longer a OHK, making it significantly weaker. I'm not saying that it doesn't make sense, I'm saying that it is not "balanced."
