Spoiler for 117 spoilers:

Yeah, Roxxane's ability doesn't necessarily make her the strongest right now, but if they don't deal with her soon she could easily grow into the biggest problem very quickly.

That said, her back story is just asking for a karmic death by a simple/ineffective technique. My vote is for Yuma killing her throwing sword shtick. It is a technique not worth copying, but in this situation, with a ton of swords scattered around, Yuma could theoretically be pretty damn dangerous.

That and I want Yuma to get more spotlight.

The other option is Cassandra getting pissed and remembering that Roxanne got her killed, and attacking her. Not necessarily changing sides, just starting her own grudge match.
