Leth I was looking at your list and it looks really fun. I just wish I had some more Daemon Princes to try and run it. This is my 2k list that I plan to be using for a pretty tough game against one of my friends. Any thoughts on it fellow EC players?
1x Chaos Lord - Chainaxe + Plasma Pistol
1x Cultists 9 man squad w/ CCW - Used as a bubble around my leviathan dread to keep him safe from DS.
2x bare 5 man noise marine squads w/ Sonic weapons in 2 Multi-Melta rhinos
3x Sonic Dreadnoughts - 1 Fist + Dual Sonic Blasters
1x Hellforged Leviathan - Dual Butcher Cannon Arrays
1x Hellforged Rapier Crew - C-Beam Cannon
1x Hellforged Scorpius
2x Hellblade w/ Lascannons.
Looks like an extremely low model count for a 2k game. So far from what I've seen is that you need at least some mass in lists otherwise you'll just get overwhelmed.
Then again...I'd like to see how far you could go with such a list, so don't mind me.
