Not sure what to think of the fact that the original question has been ignored, and we’re talking about the balance changes, but I’ll explain the reasoning for the points that have been brought up:
The changes are quite large (you could also say “abrupt” or “brutalist”) because I want to be sure I can feel what kind of effect they have in a game. In many cases I have erred on the side of changing too much rather then too little, in the hope I’ll be able to determine whether effects need to be toned down or reverted altogether. I concede this might not be wise if I also want other people to try the mod.
Ethiopians getting free Halb might be busted. Apparently you know this from experience. I’m afraid I’ll have to find out from my own experience.
Indians deserve a modest buff for 1v1s imo. Imp camel has been changed less then Heavy camel, and seeing how much I’m changing camels I’m completely unsure whether they’re too strong or too weak. It’s true camels received large stat boosts, but they received an incredible nerf to their bonus damage. Depending on how they play out they may need a nerf, or maybe Heavy camel will need +1PA. I think the camel rework will effect Indians more than access to BE, but I’m willing to be proven wrong.
The +10% age-up practically cancels out the vill discount until you’ve reached castle age. I’ve tried Indians and they did not feel strong in my hands.
Champs are being buffed against spears because spears get +1 range, and I thought it could make spears too good against infantry units. Pikes and Halbs get +1 range for the sake of immersion. It may not be important to everyone, but immersion is important to me.
+1 range Pikes is another change which is hard to balance. I suspect that in the current incarnation Pikes are too weak and Halbs are too strong. I had not realised before making this mod that Spears<<<<<Pikes<<Halbs. I left Pikes&Halbs in their current form because it’s easy to describe and I don’t have particularly good insight into the stats they should have to be balanced.
Maybe Lith have been overbuffed here, maybe not. I’ve seen someone else argue that +2 free monk techs wouldn’t be enough to compensate for increasing the Leitis price. (The free tech in Imp is more for flavour than an actual civ buff.)
I wasn’t sure whether Shotels would need a buff. They’ll still be the fastest infantry unit Ethiopians can make 
Bloodlines has not been removed from Viet, the very bottom of the changelog are “changes I’m considering, not sure yet”
The GC had it’s TT decreased to 11, making it an actually functional counter-unit to cavalry. And this isn’t just theory-crafting, I can say this from actual game play experience (against AI admittedly). On land the only other Italians change is the age-up discount increase. I decided on this magnitude because I didn’t want to over-shadow the Lithuanian eco bonus.
In the water, Italians are significantly weaker, though they do now have discounted demo ships
Their main rival, the Vikings, are also significantly weaker, with long-boats now costing more than other civs galleys. Vikings will have to rely on free handcart + mobile navy to win.
I am worried that Koreans might be the new top-dog navy civ (especially since the Turtle ships are buffed into usefulness), but only a game between humans can tell whether that’s actually the case.
For the top civ nerfs, I only saw a handful of unique options:
- vills more expensive
- age-up more expensive
- lose conscription
- lose gold mining & beyond
- lose stone mining & beyond
- lose bow saw and beyond
- lose heavy plow & beyond
- lose handcart
In my estimation, the final eco upgrades don’t really matter much, in particular you can do fine without the shaft mining upgrades or crop rotation.
It’s possible that Age is more finely balanced than I’d thought and any one of these nerfs would reduce an S-tier civ below C-tier. If this turns out to be the case they will of course be removed from the mod. @MatCauthon3 happy I’m at least trying to nerf the top civs? 
Could anyone suggest more gentle alternatives if these nerfs proof too fierce?
