I started looking at trying to move Wireth into a ranged support position given suggestions that we needed more ranged support, but I really don't think he'll be especially viable there. I took the Falconer archetype with the assumption he'd be going TWF with his double axe. Losing the 6th level combat style feat doesn't hurt nearly as much there. With his current Dex, though, he'd need the "ignore prereqs" feat at 6th level to take the ranged feats someone in that position needs.
We still have a little time until level up, but my inclination at present is to stick with my initial plan, since I think he'd just be a subpar archer given his Dex and archetype.
