The warmaps aren't balanced at all. Other than GG, Yllse is generally easier to attack than the other nations as all the stones are very open, there are no real bottlenecks. Not to mention there is a damn potion shop in sedless which the enemy nation can use.
My suggestions are the following:






The stone changes may seem small and insignificant, but they will make a big difference in war outcome. The other stones are generally fine and balanced and don't need repositioning.
If you want to bring up the argument about distance between stones being an advantage for the defending nation, it's not. It's actually more of an advantage for the attackers, since it's easier to defend stones that are closer together to each other.
All of these updates should be really easy to implement, so coding shouldn't be a problem. Cheers.
