Thanks, Kram.
I'm sure I'll get more speed on her with time, but right now it's the best I have.
For a double boost, I could use the usual suspects (Seeker, Gorgorab, Dazdurk). I may also incorporate Doomscreech or Tarshon for Def.up for the occasions when I use Ragash as a debuffer/mini-nuke.
For provoker, I could use Krisk since his A3 also increases speed for allies and he comes with shields. Also, I maxed GH bonus for Void Accuracy on my way to Arbiter, so that works out.
For CC, I can use Psylar in Stun. Can't rely on Stun much due to the low percentage, but even 1 out of 4 stunned can throw off their tune. Plus, she really slows the team down.
I think Krisk may be the best bet for me then, huh? He's in my CB team, so I'll be keeping him fast anyways.
