Gonna borrow a couple ideas from other posts:
Wither is too narrow currently, couldn’t it be a small fan shape instead?
Pan: Remove Lykaons entirely (or just make them Pan’s GP (similar to Prometheus’s Valor, turn the villager into a lykaon, who can gather faster and also turn into a wolf). I’m sure Arcadian meadow has utilities but I just find that GP atrociously boring. Move Hamadryads to Pan and adjust their stats/upgrades accordingly.
Hestia: Give her a different myth unit (Gryphons?). Her GP is really cool!
Perspehone: Her God power destroying the TCs doesn’t feel good at all for me. First of all why does it include units from other players? I would much rather resurrect 50 units that were mine (at no TC price) with a different caveat (50% HP or something like half their normal upgrades)
Would really like to see sirens work differently. Harpies and sirens feel a bit redundant (even if I do like the current sirens’ visual design, it’s innovative) so maybe remove the harpies, remake the sirens into a flying bird woman that still lures the targets away from their allies? It’s mostly wishful thinking so I would at the very least want them to have their luring ability just be a charm that lasts a few seconds and lures the target close to the siren, who then deals a strong blow. The rest of the time the siren is either a pure support unit or just attacks whatever she can. They need to be able to attack buildings also.
A general issue with Demeter because of her unique MUs is that they need a lot of micromanagement, and while I don’t shy away from a bit of that, Lykaons + Harpies + Sirens is a bit too much for me.
As mentioned by many I also feel like Harpies are a weird choice for the Fortress unit, and a very frail one at that. Would much rather have her be replaced entirely by a human unit. Not being a huge fan of Lykaons I would not be sad to see them go, Harpies could become Pan’s GP (spawn a few that act like Kappa swamp, but circle above the enemy instead, abduct a few targets and immediately drop the abductees.)
I really enjoyed being able to have 2 villagers per farm, and Hestia allowing for bigger population cap is great (though ultimately defeated by Persephone’s weird GP).
I was really hoping for another option than Hephaestus for the last age…
