Had a listen to the vox cast. A couple of interesting things stood out to me:
1) The meta Lawrence was observing was based on large 'bomb' units backed with psychic powers and stratagems, generally of deep striking horde type infantry. Examples included what Lawrence was using with 20 man Guardians squads with Protect / Doom / Guide / Discipline of the Black Guardians to support, Cultists with FNP, +1 to wound and a stratagem to fire twice, and Bloodletters.
I see that as a major issue for Drukhari, as unless the Codex changes more than I am expecting, we don't have the tools to deal with hordes.
2) The large model counts and melee emphasis meant he ran out of time in all the games.
This one is also awkward for Drukhari if tournament games don't reach the later stages of Power from Pain. Will have to see how that works out.
