Dual-wielding 2H weapons is not a good idea, especially as that would look ridiculous and secondly, as no one knows how that would work properly without being ompletely off the hook.
My bet is that it’s going to be summons. Warleader, Commander, something like that. The weapon could be any of the three non-magic ones they don’t have, shortbow, pistol or dagger, although I’m thinking pistol or dagger. I don’t think the devs are going to start giving the warriors magic this far into things, or ever will.
