Reave
[13] Hero
Dual wielding two spears that are a fourth shorter than Kilik or Seong Mina weapon would be a good varation.For me, I usually can't see anyone wielding a spear, since I'm worried it might already be too similar to Kilik or Seong Mi-na's style, and even if it does take more from the actual piercing aspect (like Hilde's style), there's no more variation than that.
Same with the dual wielding daggers, or a flail of some sort. The custom styles presented in SC3 were already using original characters's movesets for a base (and already, they even copied some moves).
