Failing to activate the Ordinatus with the re-roll (and having it break) was the nail in the coffin. With it broken I just kept on hammering it to get BTS, and with the crit I scored 3 more of DS's formations that were broken were hacked down. After that he only had 3 activations on the board and by the end of turn 3 it was 5-0 Raven Guard. There was a pretty hefty RG cassuality pile though at the end of the game (see the second to last picture, they're in the bottom right).
Short of putting them in a Thunderhawk I think Storm Eagles are the best option for the Raven Guard Assault. Between the 15cm planetfall placement and a 35cm move, chances are you can get them into base-to-base.
In terms of place style, dropping lots of speeders really puts you in a "shoot first" mentality. I find myself retaining a lot more then I do with the core Marine list (and failing a lot more

), in attempt to break another formation before it can fire at me.
Neal, I have another batrep from last Wednesday against Black Legion. It was using LI's old playtest stats though so it will be of little use to Steve. Are you interested in seeing it?
