First thing about the demo:
"Drop and go" buildings are it
So our friendly Tortured Slave (DE Builder) just starts the summoning of a building and it builds itself

kinda like how Necrons and Eldars should both build
2nd thing: The intro sucks. A lot.
Now onto various details:
DE Die like flies
Warriors and Warp beasts kill a lot.
DE Have global spells.
They need souls for said spells, souls that are gathered from random places or dead enemies by your very own tortured slave
Their relic unit is a new vehicle i didn`t get to build
