I chose the Iron Warriors. After all who doesn't like the sound of the Big Guns at your back as you charge forth into the Breach in an Imperial Outposts Walls to slaughter all those with, Making their protective Walls, their Tomb.

I see no Death Guard. How are we supposed to infect without plague marines? Actually I see only Chaos Undivided here. No Thousand Sons or World Eaters or Emperor's Children or Death Guard. We could use some specific God worship factions. Though out of all of those listed in the poll I'd probably go with Black Legion.

God-specific legions are planned for release POST LAUNCH

As Ulfgard stated, its planned post launch.
However on launch God marks will be present as loadout options (probably earned too), so we will indeed be able to spread Nurgles gifts.

If i could go World Eater I would but Black legion (in my opinion) is the best up there

Iron Warriors. Perturabo's Sons shall level every enemy bastion, casting down the walls of the tyrannical Imperium just as they did at the Imperial Palace! And in their place shall be erected towering fortresses of black Iron and stone.

My only regret: There are no Imperial Fists in the game (yet) for me to prove my Legion's supremacy in Siege and Defense.

IRON WITHIN! IRON WITHOUT!

Word Bearers, never deny KHORNE

Ave Dominus Nox !

I feel the same friend very much so

Since the World Eaters haven't been announced (Yet) i'll have to go with Night Lords. I really like the Night Lords mostly because they are the hunter and use fear to their advantage, and they usually dont just run away in fear, but also because of the Warp Talons which are complete deamon/marine predator!
