I feel that the hammer is a better arc blade. Cauterize is a better version of hungering blade, as it can be activated by any fire (at a range). The arc blade super has less damage resistance and significantly less range. I will say that bladedancer has quickdraw, arc bolt, and blink, but the Sunbreaker has fusion, as well as to move faster than all other classes with skating. I don't think it needs a huge nerf, but I do think it is clearly overpowered. I, like most people, would like the super to provide less damage resistance.
