There is a rebalance for ya. The map of EC is unbalanced :p all the big cities and rich townslands are focused in the south where Perdan and Isadril are.
Not completely true, but the bigger cities and rich townslands do seems to be much more concentrated in the South. The North does have big rich cities though: Fontan, Oligarch, Sirion. But, so far as townslands go, not many, especially in the far North. Trinbar is pretty rich, Pucallpa pretty poor(and horribly located strategically speaking). Negev and Al Amarah are rich.
But, in the South, they have Isadril, Itorunt, Perdan, and in the far South, a city nearly every few regions that is richer than Ashforth, Kazakh, Slimbar, and Karbala. And then they have the multitude of townslands that the North does not have(and the mines of Isadril).
If the normally high gold producing regions are going to be concentrated so much in the South then the gold concentration needs to be cut a little bit so that the North can compete without having 20+ regions.
