BFME fans, if there was a BFME 3 made what features would you want it to have to make it stand out?

I personally think it would be cool if they focused on The Hobbit films. I know those films are pretty controversial but it seems like a logical next step for the franchise. Have the campaign follow the films and include factions like Erebor, Dul Guldor, Laketown, Gundabad and the Woodland Realm.
