I have to admit LKHERO that i feel the reclusiarch is useless with DC. The difference between a reclusiarch and a normal chaplain iirc is that the reclusiarch makes the unit fearless. What is the point of this if you add him to an already fearless unit. You're better off buying a cheaper elites chaplain imho.
I think the stormraven can work competitively but i think you need two. One will get casually shot down with a lascannon. But two moving flat out with a 4+ cover save will be more troublesome i think.
