-A wave two for the Idoneth - yes, I’m well aware that some of us are sick of Aelves, but there’s so much awesome unused design space for the Deepkin. Some specific things I’d like to see are: a big Kraken behemoth, some Namarti riding giant crustaceans, an assassin unit that uses special Jellyfish toxins, maybe some more named characters? Oh and on foot Akhelian infantry.
-Necron style reboot for either the Skaven or Seraphon (preferably both). It goes without saying that the poor rats and scales have been left in dire straits for far too long and they really deserve some TLC.
-Revamps for the Spiderfang. The Arachnarok can stay cause it’s an iconic model that aged really well, but some new Spider Riders and Scuttleboss would never go amiss. Plus maybe the Scuttlings from Silver Tower? They seemed like they were gonna be a thing
-New Duardin faction! It’s probably been said and will be said again a million times ad nauseam but a Lumineth-style revamp for the old dwarf range with that AoS flavour in it would be lit. We’re talking Gholems, big war machines and - possible hot take incoming - mole cavalry.
-General expansion for some of the smaller factions, honestly. Throw the Fyreslayers and the Sylvaneth and the FEC a bone (literally for the latter) and give them some variations on the same old units.
-Please don’t obliterate me for this, but River temple and the other mentioned Vanari units (them chariots and scouts) for the Lumineth. But this is like, after every other faction has had their stuff, so 2-3 years.
-And last but not least, Beasts of Chaos? Pretty please GW? But a crumb of new, even somewhat competitive content or even acknowledgement in the lore? Pretty please with a cherry on top?
