I know nothing with regards to blood angels special rules or characters so if the following does not apply then I apologize ahead of time for being ignorant
It all depends on the armies you face of course but I think assault marines are gak.
your attack bike and the dread will get targeted real quick and that leaves you with very little anti armor. I assume you will need those marines with a melta to support your assault and tar pit other units OR hold objectives keeping them out of the fight altogether. There isn't good enough target saturation because assault troops just aren't that menacing, especially the ones footslogging!.
and the two baal pred will be useless if your assault is in top gear.
I suppose the
HQs are the difference. I honestly don't know much about how the characters play out.
idunno, i just don't see how this army plays out well against
CSM, orks, nids or MECH Guard...
