1. IMHO, there is a need for a neutral and good version of the Dark Cultist.
2. It would be cool to see a character with the abilities of the Royal Masons or at least the ability to remove Freeland tokens.
3. The City needs some new cards. These could either come out with the next expansion or be a new expansion to the City Expansion itself. The obvious characters to include would be the Sheriff, King's Champion, Master Thief, High Mage, Animal Trainer, and High Priest.
