The major change I would like to see is an option to disenchant troops for other resources. I don’t need the souls as much anymore and it would be nice to have an option for the extra troops. It also has a way to get the resources you need. Maybe something like a Soul Concentration to get trait stones of the troops color. Similar to increasing the strength of the troops, but sacrificing so many to get a trait stone of a particular color. This could be used for gold as well.
Minor would be mass disenchant, mass map usage, and something done about major trait stones.
On a side note I really like the idea of the individual boards for kingdoms, something to change it up.
