About the Greyjoy campaign: isn't Theon supposed to be imprisoned in Winterfell.
Personally, I'd be happy for you to send him away, he's a terrible general and his loyalty is bad.
Loyalty is a BIG problem with the Greyjoys.
All character traits are more or less WIP. They're in need of an overhaul and balancing. Theon will stay with the Greyjoy faction though.
"Five had been his brothers. Oswell Whent and Jon Darry. Lewyn Martell, a prince of Dorne. The White Bull, Gerold Hightower. Ser Arthur Dayne, Sword of the Morning. And beside them, crowned in mist and grief with his long hair streaming behind him, rode Rhaegar Targaryen, Prince of Dragonstone and rightful heir to the Iron Throne."
Everything else wouldn't make sense, as his loyalty is certainly not with the Starks.
Truth of the matter is, I think his loyalty should stay as crap, the man was not really loyal to anyone but himself. He is arrogant, cocky, and only thinks of himself. Not to mention the man is sadistic and lets pride blind him to reason. I mean, staying in Winterfell just so that he could have a castle all to himself, how ridiculous is that. Asha was right, he should have seized the castle, sacked it, taken Bran and Rickon hostage, and then retreated back to the sea before anyone knew what the hell was going on. Had he done that, he would have been regarded as a genius and a bold commander and he would have ended the war at a stroke, undoubtedly earning the respect of his father and the rest of his family. He also should have left with Asha when she asked him to, she was right,he didn't stand a chance and the only thing that made him stay was his jealousy and pride. He even asked himself why the heck he stayed. Also, what was with trusting Ramsey, a.k.a Reek. He did not know the man. He also should have swallowed his pride and given Ramsey whatever he wanted after he just saved his ass as he was in no position to say no. He also would have earned the Greyjoy's a powerful ally. He should be a good general though as the plan that led to the fall of Winterfell was genius.
