I have started several games and in only 1 of them have I been able to found a city near a gold mine.
In cities that do not have a gold mine, I build merchants and markets and send caravans so I can build up 80% economic bonuses. But since the city does not "produce" gold, there are no bonuses. Taxes are under "Misc" and not factored into the bonues that I can tell.
1. Is this the way the economy is supposed to function?
2. Am I missing a building to produce gold rather than giving 25% bonuses?
Also, if I could suggest a rebalancing of champion item cost vs. unit costs.
I like a lot of the changes in the beta. This is my feedback to make the game better, not a complaint.
