I would put rank discipline on both oathsworn instead of master crafted weapons.

Yeah , good idea , last game I was using the Daqan and never saw any use for the master crafted weapons.

Also Fallen Hero does nothing here.

I think you would get more utility running both archers as 2x1 with combat ingenuity it would also free up some points for other fun stuff like Fortuna's Dice on Ardus or the Infantry since as @TallGiraffe stated there is no benefit for the fallen hero currently unless you are just trying to add a bit of my HP in one of the trays. (fortuna's dice on a hero is soooo fun)
