Just a few suggestions, not to make the game balance perfect but simply a bit fairer or more exciting.
General:
-
Elephant archers: in the PUP they get -10f and +3 cavalry archer armour class. This is a start, and we should see how this would pan out. However, I would argue that given the cost of the unit, it still isn’t good enough. On top of that, I would: increase their accuracy to 80/90%, increase their attack to 7/8, and make parthian tactics affect them as cav archers (Bengalis only, this means +4 against pikemen instead of +2). Of course, this is a lot and should be proceeded incrementally, but my logic is simple: if you have to pay so much for a unit, it should be powerful, especially if slow. And they would still die to skirmishers and mass pikes.

Steppe lancers can be occasionally used with the Mongols, but otherwise they remain quite niche. The Tatars can just go for their much, much better Keshiks, and the Cumans’ are simply created faster. More importantly, the elite upgrade is expensive and does only bring +2 attack and +20HP. Whilst not terrible, the elite unit is almost never appealing in Imp, either because there is a better gold unit to go to (Paladin, Keshik, Cavalry Archer, Mangudai), or because gold is too scarce, and all three civs prefer using cheap Hussars for raiding. On top of that, Hussars have almost the same HP, and more pierce armour. So I would propose to give Elite Steppe lancers +1/+1 armour. If you compare it to Keshiks or Winged Hussars, I think this is reasonable.
Civilisations:

Bengalis clearly need more, but their team bonus should be at least 25% food on top of the trade gold. Spanish get +25% gold, and when trading, gold is an extremely valuable resource, more so than food 99% of the time. So +25% food would still not be as good as the Spanish team bonus, but would make more sense…
-
Burgundians: on top of other changes (PUP), Cousilliers should be +5f/+5g to 60f/60g. Flemish Revolution should get out of the game entirely, but as this is probably not going to happen, change it to: “All villagers garrisoned become Flemish Militia”.
-
Cumans: Cuman mercenaries also makes Steppe Lancers 20% cheaper.
-
Goths could get the loom instantaneously and free upon reaching Feudal Age, on top of being able to research it in Dark Age. +10 max pop → + 5% max pop. +5 attack against boars → Boars last 25% longer.
-
Gurjaras: A lot has to be done, but +40% bonus damage for mounted units instead of +50% is probably not enough of a nerf. I would try +33%.
-
Hindustanis: same as Gurjaras. Camels attacking +25% faster on top of Imperial Camels is mad: remove this entirely! And this is supported by an amazing economy, and fantastic counters to everything. Shatagani +2 range is probably too much.
-
Huns: rename “Atheism” into something else (like “Tengrism”).
-
Incas: Andean Sling -150g.
-
Khmer: loose access to Hussar. This does not make sense historically, and they received it because the rest of their game plan was considered weak. Since then they became significantly more powerful, and FU light cavalry with better farms is already very good.
-
Poles: non-elite Obuch -1 PA. Obuch +10f.
-
Portuguese: Feitoria are a nightmare to balance: 3 ideas: (I) Make it a building like the caravanserail of Hindustani, which increases the resource content of all resources within a range (e.g. like +50% gold in a mine within 10 tiles, same for trees). Then make it cheaper and smaller, and only cost 5 population. (II) Make it generate only food and one other ressource, which has to be decided from the player. All Feitorias can only generate this one additional resource at the same time. Of course, gather rates of gold, wood and stones would still have to be different. (III) The gather rates of Feitoria are working like now, except that they are based on the initial amount of resources on the map (with Maxima). The way, the Feitoria does not generate too much wood on Islands.

Sicilians: reduce the Donjon cost by 25w.
