Well, we keep talking about Gastone over in the Llael thread, how about over here? I think the obvious option is Steelheads for their many numbers for cheap souls. I'm thinking a good balanced list with quality guns and solid melee is the way to go. I'm thinking Nyss would fit that bill perfectly and with Dauntless Resolve, they would make it to combat pretty reliably. The feat turn can make for some really impressive options to get them into places they shouldn't be. Croe's might be a great option here too for many of the same reasons.
Has anyone had some success with him in Irregulars? Any interesting ideas running around?
Nyss don't seem like the ideal target for dauntless as they don't really benefit from the arm portion. Forge Guard (arm21), High Shields (arm22, or 18 out of shield wall), and Steelhead Cav (arm20+boxes) take best advantage of it.
