A few suggestions, largely relating to house and city management:
1. Chat rooms: I'm loving the chat function, but I'd love it even more if we were able to create our own chat rooms. This would make it a lot easier to form alliances with other houses, talk to house members in cities that haven't been absorbed into a tiered-up house yet, create an "announcement board" for people who don't have time to scroll through the house chat to receive important messages, and otherwise customize the way we interact with other players on the map.
I have suggested this in another thread so fully agree on this one.
2. Number of officers: The number of officer positions should increase in proportion to the number of cities a house absorbs. Since only officers are able to keep the city governor title after they log off and log back on, this makes it frustrating and difficult to assign semi-permanent city governors for houses that have more two or three cities under their umbrella. Since the number of house members will also increase with every city absorbed, it would make sense for more officer positions to be available to manage more people.
I would add some more positions on this one.
Now if am right there is a normal member, minister, governor and lord.
But actually they have the same rights and can all aprove new members and promote/demore players.
Maybe a specific position that controls the rights but can't change someone else rank.
Or a diplomatic if there is a better way to have alliances.
The higher your rank is the more combined rights you have.
5. Alliance indicators: It would be great to have some sort of simple, formalized way to indicate that two houses are allied. This would make it easier to communicate non-aggression pacts to new members and serve as a constant reminder to old members who a house's allies are. Literally just a line of text or a badge somewhere in the main city screen would work.
Totally need this one, with a diplomatic position like mentioned above.
