I still haven't found a setup for AI Edge that can...

...compete with Meracle's X-Claw or Arumat's Dragon Roar. What am I missing here?

Team is Edge, Reimi, Arumat and Sarah, with Reimi on Manual and everyone else on AI.

Edge was not meant to dish out aoe damage but rather he's just a really easy character to use and start with. Just fill his skills with raging strike and he'll only do that attack. You're pretty much guaranteed quintuple 9s if it crits.
Otherwise side him out and use someone else.

If you're looking for something to decimate the battlefield try out:
Meracle's x claw
Arumat's dragon roar
bacchus black hole sphere (incredibly broken skill... what were they thinking?)
And well... anybody, even edge would be great here as the black hole sphere sucks everything in to the middle and his raging strike will hit them all for quintuple 9s every time.

Alright, I'll give Raging Strike a try. The only other skill I've found somewhat usable is Cyclone Slash, and it still has a lot of wasted frames.

Anyway, I'm working on my ultimate gear now; every character will get this same exact loadout. How does it look?
