Dunno, on my full play through of the beta, for the main chars I had one warrior and one hybrid - Shadowblade and the Shadowblade ended up being more versatile and powerful than any of my companions or warrior, just depends on how you build your hybrid I guess.
Having one hybrid as a utility char also seemed to help rather than wasting ability and talent points better spent on "main" stats for your non hybrids. At least for me.
