Especially ones that can kill your Greater Daemons on turn one with some heavy armed flyers or lascannons.
You will have trouble with fast (Space Elves) and shooty (Guard, Tau) armies - always.
Not a lot of cheap anti-horde capabilities (besides Slaanesh) compared to enemy horde point costs.
Prepare to spend CP on the deep strike stratagem if you don't want to run the risks of footslogging.
Lackluster mobility (unless you're running Slaanesh): Your Stratagems make summoning better, but it's still rather annoying.
You really have to get up close as fast as possible, on foot because.
Daemons have a low leadership value compared to other hordes and only one option to improve it a bit (place a Greater Daemon near your hordes until he gets lascannon sniped).
You can play hordes, but your hordes cost quite some points, especially in comparison to other hordes (Orks, Tyranids, Guard.).
The fact that Furies (who are supposed to be Chaos Undivided incarnate) have to take marks is a big hint.
Looks like (rumors!) Chaos Undivided won't be a big thing in the future.
You need quite a lot of miniatures, and the big ones aren't cheap, but you wanted to sell your firstborn child anyways, didn't you?.
5++ is something but not much, and you have got a lot of T3 units.
When mixing Gods, you can oversaturate target priority, makes them stress about what to shoot.
9th changes make Daemons fantastic at board control, lots of variety in objective holders and takers.
It's almost like having three armies for the price of one.
Your army is completely compatible with Age of Sigmar, kill team and The Horus Heresy.
Your Daemon Prince murder machines can hide behind other troops.
Many units with FLY wording for disengage engage shenanigans or for charging those annoying DEldar fighters and bombers.
Space Marines and other expensive armored units will hate you for that. Your daemon spells are meh, and buffs are limited to daemons of the same god, but you can spam Smite all over the place. With an instrument, you'll get +1 to charge and therefore need an 8 (42% chance) - doable with CP re-rolls
Possible charge after (now fucked up) summoning.
Build your army on the battlefield with summoning (but now in a very fucking crappy limited fashion).
Probably even more mixing with CSM (Daemonkin) later on and, therefore, even more different units to use.
Lots of different playstyles with 4 different gods, monsters, hordes, magic and so on.
Daemons and Thousand Sons together is one of the best armies in the game right now, with some of the best untargetable characters hiding behind an obscenely tough swarm of troops.
Wide range of miniatures, so painting never gets boring.
Tzeentch and Nurgle make your guys even tougher.
Armywide 5++ save so you don't care about AP.
If you always wanted to command an army entirely composed of bizarre and horrifying monstrosities (and who didn't?), then Chaos Daemons are for you. Each one of them is an incarnation of the Dark Gods' will made of pure Warp energy, and therefore mortal concepts such as fear, exhaustion, or pity are alien to them.
8.9 Special Note/Tactic against Imperial Knights (and similar Titanic models)Ĭhaos Daemons are the ultimate enemy of the Imperium, perhaps more so than the Chaos Space Marines who worship them.
