I will play Chaos! I love the fact that the Chaos ( at least in Warhammer classic ) is connected to the northlands. I come from germany and im really interested in the nordic mythology so i can identificate myself quite well with Chaos/barbarians/marines. Ah and I love Nurgle I really hope that you can choose your God when you play as a Chaosspacemarine . Maybe skilltrees like : Nurgle=Tank/Heal Khorne= melee DD Tzeentch= Range DD Slaanesh=maybe a bit rouge like Just a little idea . but not sure about slaanesh and tzeentch
