Like most of you, I do agree that that Chinese need some drastic adjustments here and there, but this isn’t a post about that but rather what is missing. After playing Chinese every day, I have noticed that they could have even more replayability if they had minor god techs that affect siege.
Units like Axe Cart and Siege Crossbow are very situational units and could see more use with some minor god techs.
While comparing old civs to chinese, I noticed that Greeks also have some space for siege techs.
I will give some ideas:
Xuannü (Classical age) is goddess of military strategy and has space for 1 more tech due to having less than others. She could have tech that unlocks Siege Crossbows age earlier and removes their minimum range.
Nüba (Heroic age) already has slight focus on military academy but due to lack of cav/infantry techs is locked into ranged units. Could have tech that gives siege engines +20% hitpoints and +1.0x bonus vs heroes. Siege engines would also synergise with her Drought godpower well.
Zhurong (Mythic Age) has same problems as Nüba providing no bonus for infantry, cavalry or heroes so lacking proper frontline. He could have tech that gives Axe Carts +30% speed and +20% all armor.
Regarding Greek.
Artemis: To follow up on destructiveness of earthquake, she could have tech that makes siege weapons shoot +1 projectile (so +33% damage).
From the list you give us :
• Xuannu : I agree with your idea… She should give every military units from Classical Age including siege units…
That will maximize your potential early raid chance since her myth unit is Qilin that only give you healing buff and not some tanky monster like Houtu’s Qiongqi who stronger when facing many enemy units or sneaky Chiyou’s Yazi who can suddenly teleport to your units
(also she focus on military production which is why she must grant you tech that enable every military unit for you to use)
• Nuba : for her, she focus archer and myth unit which kind of difficult implement upgrade for cavalry and infantry( melee military units)… If only she can give one more tech that allow your archer and ranged siege units to give enemies building and units dps … would be awesome
• Zhurong : he is god that focus on myth units and farming which, of course, he can’t grant much tech for military units since its not his focus… Maybe he can grant one tech for military units that increased their attack speed and run faster if they encounter enemies and reset when they run from enemies without being attacked for 4 seconds
• Artemis : her focus on archer should give the archers 25% not just 10% (10% doesnt do much damage even if it is poisonous(her tech allow archers to shoot poisonous arrow) )
That’s what went through my thinking… If there is anything I mistaken… I am sorry
