I just got my first few World Eaters minis from Combat Patrol magazine and have a very large pre-existing collection of Khorne daemons from WFB/AOS. Are daemon-heavy lists really viable with this codex? I'm debating fleshing out the army if it's not too big a project. I'm far from a competitive player so meta chasing isn't important to me, but nobody enjoys a turn two tabling.
