The recommendation would be to use the Dome illumination as a supplement to mesh lighting.  Outdoor scenes may be more forgiving than indoors; take into account what type of ambient lighting is provided by the HDR and build your stage lighting accordingly.  Basically, think of cinematic lighting rather than relying on how your eyes interpret the scene.  We are so bombarded by TV, movies, and commercial imagery that when we actually take a photograph of our own, we come away disappointed at the results because of perceived expectations.
