Question? I don't have my blood angels codex anywhere near to hand, but I thought a Chaplain came with d3+3 Death Company members. ( Thats why he's so darned expensive points-wise). I didn't see them reflected in your list, and it seemed as though you were awful thin on the ground, even for 400 points.
