Ok so I rearranged some stuff. Took out the sternguard and a Baal Pred. Added a stormraven, turned a squad of assaults into small death co w/ 2
PW to ride in said stormraven, and added death co dread with talons again to said stormraven (just sounds like murderous fun). Upon looking at this list I realize that I have no template weapons and a lack of "volume of fire" units to kill gaunt swarms/massive boy squad/powerblob
IG and blow stuff out of cover if needed. I mean, I have mephy to assault stuff in cover and the death co can all handle themselves admirably so I guess unleashing the death co dread into a powerblob would be entertaining

It should also be noted that if I go with this list, I am going to paint and mod that stormraven to look like a reaver ship from firefly complete with bodies strapped to the hull.
