In which city is the alt upgrade more balanced?

I think the balance in the Castle faction and overall is still the same as it was in the previous edition! I also like how the Academy and Haven factions are balanced.

But in my opinion, if any faction suffers from poor balance, it's Haven...
Just look: Archers are definitely better than crossbowmen, Zealots and Adepts are also stronger, and Landlords are stronger than militia, in my opinion. That leaves only Paladins with Knights and Archangels with Seraphs, and even there, the choice isn't clear...
