swapping in a weapon for BS is pretty awful tryhard. the only time its really worth doing it is if you already have something like a primal and claw of lightning and you dont have to swap the weapon from one hand to the next but just hover over the primary with your epic for swap. the epic is the best weapon for swapping because it has the highest weapon damage and an innate attack bonus. outside of significantly better weapons like vyemm, primal, or doze the swapping probably isnt worth the marginal increase in dps imo.
