I like the typhoons and Ezekial
Also foot slogging can work for
DA, see a good number of deathwing lists.
Dev. squads are expensive and
tac. squads are a little pricy for their capabilites. I would choose 2 of the same weapon for the bikes to do a job well, also probably going for plasma guns to keep them out of
cc.
I guess you are looking to use Ezekial and tactical squads.
You need transports for the tactical squads. I would use laserbacks or drop pods.
You look for a razorbackspam sort of list taking to account laserbacks and the cool stuff
DA can and cannot take.
Ezekial
Squads with laserback, 5 men with melta and maybe a powerweapon or meltabombs.
Annoyingly deathwing fit this approach.
3 typhoons as they are cheap.
3 preds to provide the extra covering fire.
Else the drop pod list. This relies on entering everything second turn onwards - this is probably the safest way to drop pod. Given the ranged capalities inside the
DA codex you can keep them guessing.
Ezekial
10 man tactical squads in drop pods
Then some other units in drop pods
Annoyingly deathwing fit this approach. I read the deathwing assault is decided on the first turn, so you can always put them into reserve to come on after turn 2 but then change your mind.
