I havn't played much A4. But back on-topic. How do you think Jeff will implement the "play as a servile" thing? It would make no sense Shaper's-as-a-faction wise. Maybe the Shapers aren't a sect? Oh, also, three classes taking the place of Guardian, Shaper, and Agent. In G4 at the beggining, maybe you choose a job? Say, Alchemist/Sage (Shaper), Constable (Guardian), and Thief (Agent). From that point you are a normal human/servile. However, you have been expressing serious doubts about Shapers and the treatment of creations. During this time of war, Shaper's execute anyone expressing "rebellious" beliefs. But before the soldiers they dispatch to "take care of you" arrive, the Rebels approach you. They offer to give you a canister that will allow you to Shape, and teach you how to Shape. Fast Forward 2 Months. You have just finished the basic course. However, that's when the Shapers attack. From then on you are free to join either Ghaldring, Greta (who has become an important advisor) and the Rebels, What remains of the Shaper Council, Alwan (who is an important General), and the other Shapers, or the
Awakened Alliance, made up of Humans, Serviles, Shapers, and even a few Drayks. All they want is for the war to stop. They are led by Learned Minar, Shaper Rean, and the wise, old, Drakon Fhethrar Blaze. You can question your Rebel training, become a Rebel, or join the AA, and try to end the war.
EDIT: The Shapers, in their darkest hour, will let you join if your a Servile, because they need everyone they can get. They wouldn't be as nice to you, but you could join. And betray your own kind.
