Saracens
Overrated, even if they can abuse market, that doesn’t make resources magically appear from somewhere. They’re win more civilization meaning they can close out games in situations where you should win anyways.
I do think that archers shouldn’t break buildings by themselves, maybe the arrows could make the building take more damage from melee attacks for certain duration. Obsidian Arrows is the real issue considering Mayans have actual eco bonuses.
Lithuanians
Lith eco is subpar and the monk thingy is high rolly. I don’t like the idea of +4 attack in castle age though. So they definitely need to ladder the bonus to like +3/+4 or +2/+4 in castle/imperial age.
Bulgarians
Bulgarians are already amazing, tanky 2 handed swordsmen, hussars with stirrups, Elite konniks that beat FU Paladins. Even Bracer. One of the only civs that can afford to upgrade their siege fully. I don’t think they need buffs. They do not need stronger ranged units, they have great melee units and good scorpions/CAs/skirms/Kreposts/SOs as backline already
Tatars
Don’t need nerfs other than Keshiks needing to cost a bit more. If there would be a nerf other than that, it would be removing Hussar from them as FU light cav with +1/1 armor should be still better than FU Hussar.
Vikings
Yea Chieftains should be cheaper again. They get all Hoardings, Masonry and Architecture, maybe removing Hoardings or Architecture would be decent so they can’t hold the map as long with their castles.
Byz
Yes, town patrol should be free.
Spanish
They are fine, I don’t feel like Conqs need changes. Conqs falling off in imperial age is normal, its life of high HP ranged units that try to fight mass archers/cav. You would need to micro 3 times more than the enemy to not waste damage considering 90% of them will try to hit the same target otherwise.
Spanish have Paladin and great team bonus for imperial age. I don’t see any reason to change them.
