I have been living in Whitehelm because chicks dig heavy armor. The bonus is 20 glory x2.
Has anyone found a more efficient kingdom for use with the new updates?
Also, I was thinking of going with a kingdom having the most uniform distribution of gold, glory, and souls.
Here you have all number, so you can do your choice 
Confusing data. For example, Pan’s Vale is listed as 25 gold, 8 glory, and 2 souls. In game, it is 50 gold, 16 glory, and 8 souls.
I’m still leveling kingdoms, so I use Khaziel, at normal 250 gold, doubled once from home kingdom and again due to gold star = 1000 gold 
I’ve been stationed in Whitehelm since 2x tribute was a thing back in 1.0.7. Glory is basically the gems of the lesser resources, in that it is versatile for so many things.
I hadn’t updated my guide for 1.0.8 until just now. Pan’s Vale is now 25 Gold, 8 Glory and 4 Souls. Given the numbers you have, I suspect your figures are doubled because you have Kingdom Power at 1 gold star for Pan’s Vale?
Yes, that is it. I see. I do have one gold star for Pan’s Vale. Thank you @actreal for clearing that up.
