-Google+ Friends
-Messaging System (Between Clan Members and Friends)
-Friends System (Not only clan members)
-Player Wall(Where anyone can post messages on your wall)
-More single player missions (Maybe when you finish all single player missions you get the 'Goblin King')
-Search players
-Task forces (Huge map which is difficult and is raided by clan mates and you and when you destroy something e.g a builder hut when someone else is doing it that builder hut would be gone) and it could have the same theme and feel like the single player missions.
