One of my favorite boards. The only problem comes with a bunch of defensive players. Games can end in stalemate due to huge build ups of armies. Card values resetting at some point might resolve the issue by providing more incentive to break through your opponents lines.
Overall, I like the board and the game play. As Oatworm noted, the default fog setting is essential to a fair game. I would like to see the Shrines changed a bit. I think that without the unit bonus, and with a lower unit count they might get used more often to uncover the fog, rather then just ignored as in most games.
