Am I wrong, or can Slaneesh dreadnaughts be made into the nastiest assault monsters ever? I don't play Chaos, but I was reading through the codex, give 'em and extra CCW, the mark so they have a Warp Amp, a Heavy flarmer (to upgrade to a Doom siren). And give them a blasphemous rune. You then have a model with 4 attacks, hits on initiative against targets in cover, and enemies are -4 to their lead checks!!!!!!!! Holy crap, you'll be able to wipe out huge sqauds!
