Thanks again, guys!
I do have one of each Greater Daemon, so I have some options there. I just don't fancy the idea of doubling up, both for expense, and because I think multiple Greater Daemons look a lot less striking. Skarbrand is an exception here, as his model is sufficiently different.
As for the advice:
Wrath of the Everchosen looks like it's the perfect time to get into
AoS with Daemons. Well, I think it's a sign from our Lord and Saviour,
GW.
Khorne: It's a shame, as I love Khorne the most of all. However, he does seem to have a force most reliant on Mortals. The Mortals look great, but I just don't have the ability to invest. I'll give a pure Daemon list a whirl at some stage, but perhaps down the track.
Nurgle: No one seems very enthusiastic about the smelly boys at the moment, Daemons or otherwise. At least Nurgle Daemons are semi-playable in
40k, so they might have to keep their home in the grimdark for now.
Slaanesh: As mentioned, I do have 1
KoS, so it looks like I can make a workable list. And that's all I really wanted; I didn't want to power game, or go super competitive. It seems the consensus (and correct me if I'm wrong) is that 1
KoS and the other heroes (Syll'Esske, Epitome, Heralds) will make a workable list. I'm glad, as I love my Perverts! Glad to see they're an option! I'll have to pick up a Fane, though, but that's no problem.
Tzeentch: Well, it seems that Tzeentch has been storming the
LVO, and perhaps I should have mentioned before that, playing TSons, I have a good slab of Gors of various kinds (Tzaan, Shaman, and bow-boys). I even already picked up an Ogroid and Gaunt Summoners (on and off disc) as replacement Tzeentch
DPs and Heralds (disliking the
GW models for these), so I'm actually pretty flush with Tzeentch. I appreciate that it was more a certain list (or sub-faction: Changehost) that swept
LVO, but it is telling that Tzeentch in general is in a good spot. I have no interest in chasing the meta, so I'm hardly going to follow that, but that I can take a
LoC, some horrors, and flamers makes me happy (i.e. core Tzeentch), and I won't be able to resist chucking in some chariots. My only issue is that a magic/shooting list might not be he best at learning
AoS fundamentals, it being more melee focused (as all good games should be - looking at you,
40k).
TL;DR: So Tzeentch it seems to be, while having non-spammy Slaanesh in my back pocket. Hope that in running these two armies in non-spammy way (no triple-
KoS, no Changehost) won't make me too many enemies, given the state of the meta
