I made a spreadsheet to track my kingdom progress so I don’t have to keep clicking in-and-out of different kingdoms. I also used it to analyze the numbers a little bit. In doing so, I found that the Pridelands tribute reward is slightly more favorable than every other kingdom.
If you look at Khaziel, Khetar, and Whitehelm you can establish a currency ratio of
250:10:40 Gold:Glory:Souls. Using that ratio, you can derive the value of each Kingdom. Converting all kingdoms to only gold is as simple as
Gold + (Glory * 250/10) + (Souls * 250/40). Every kingdom is valued at 250 except Pridelands is 275.
Maybe I’m missing something and this is balanced out in some other way? But, it doesn’t seem that way…
