Everyone's IPH is up. Most factions have maxed out their bonuses. How about adding another 5 levels to each of the current bonuses to give us goals we can strive for. Some new bonuses would be nice. While we were upgrading there was more raiding going on as faction members tried to out do one another.
How about buildings you get in the faction that the faction has to buy and if you leave the faction you lose the building. Give it a small footprint so it fits anywhere but it has to be upgraded by the faction.
I would like to have a Western Union building so I could send game cash to others, but I know that's asking for a lot.
