Arc Blade is the only super which requires you to get in close to get a kill. Every other super out there can get in close but it is purely optional. No one is scared of an arc blade anymore because as they have distance they have security, and if they get in close they can simply shotgun and melee a bladedancer by timing it right. Granted you can shotgun melee other supers but that's only if you get in close and all have ranged attacks while in super. Arc Blade needs a slight armor buff due to its close range nature, it also needs a movement speed boost because you literally can just run away from an arc blade or just float above it because the arc blade will get short stopped every time. Also, if an arc blade is able to hit a striker right before he activates his fist of havoc, he should be able to kill the Titan, UNLESS they are running unstoppable. This will at least give the arc blade a small fighting chance and even things out between the two subclass supers. TL;DR - Arc Blade needs a slight armor buff, movement speed buff, hit detection fix/no more short stopping, and should be able to kill OHK supers such as FOH and nova bomb if they are able to get that close (unless they are using unstoppable or skull of dire ahamkara). Arc Blade is by far the weakest super in the game currently
