My post will have spoilers and I'm not going out of my way to hide them in a thread called "A Feast for Crows Discussion (Spoilerific!)" If you've read this far and haven't finished the book and don't want anything spoiled you deserve to have things ruined for you.
To address some things in this thread already...
The whole deal with Cersei, Margaery and the moon tea and all that. It was all a massive setup to get Cersei busted. Pycelle didn't come forth and admit to cersei about the moontea until after Cersei confided in her good friend (who wouldn't bring her child to court) about needing a way to get rid of the young queen. Taena, Pycelle, margaery... they were all in on it. Probably the greater work of the queen of thorns, but who's to say at this point. Cersei is going down and Jaime has come to his senses, though Cersei really fucked up in bringing holy crusaders back into it. Those guys are going to cause all kinds of trouble.
One thing that really jumped out at me was the last Sam chapter. First off, the Citadel, who live to serve, are clearly more than that if it was them who got rid of the last dragons because the realm they were building had no room for magics and the like. So now the Citadel and the maester's have a greater agenda as well. Second, Pate died in the prologue, who introduced himself as Pate to Sam at the end?
Brienne is awesome and Catelyn is still pissing me off even while dead. Thoros seemed to indicate that Beric is no more, possibly as a result of giving Cat the kiss of life. As to what Brienne yelled as she was about to die that might save her, Arya seems as good a word as anything. I'm just upset that he'd leave us with such a cliffhanger.
Robert's Bastards. Sadly, I haven't read the second Egg and Dunk story in the other Legends book. However, we know now from Aemon's mumbling that Robert/Renly/Stannis's mother was Egg's daughter. Considering his bastards still have great relevance to the narative, I'm guessing it has more to do than just them having a King's blood in their veins as melisandre wanted to burn them. Unless she gets a dragon and everyone wants to sacrifice one of Robert's bastards to get dragons, which would just be dumb.
Arya. I had a feeling that the Arya chapters that were included in this book were only there to play along with Sam's visit to Braavos and that we'd see more in Dance. Anyway, learning more about the faceless men and the way they become completely different people supports my belief that Syrio Forel and Jaqen H'Ghar are the same person, not that it has much relevence at this point. Sucks to get cut off with her waking up blind, but if it means we get more Arya in Dance as well then I'm all for it.
The Wall. Something awful is going to be going down at the wall. It's getting fortified and they know how to deal with the others... but I have a feeling that The Others are going to be pawns compared to what's going to attack the wall. The wall has magics in it that keep the others from passing, as seen with Coldhands not being able to cross and also in Jon not having wolf dreams or being able to sense Ghost when they were on opposite sides of the wall (Yet Arya was still "connected" to Nymeria while she was across the world in Braavos).
I hate the ironmen and want them all to die. Interesting how the horn that can allow someone to control a dragon kills the person who uses it. Maybe only certain people can use the horn to control the dragons. Maybe it'll help Dany keep her babies from eating kids. Who knows.
I really liked what's going on in the Erie as well. I was starting to lose faith in Littlefinger's scheming and plotting, but he totally made up for it at the end of that last (really long) Sansa chapter. Can't wait to see where they progress from there.
THE MOUNTAIN THAT RIDES. Holy shit, what they hell has Qyburn created with his dying body and who's going to have to face it in battle? I *need* more details on what was going on in that dungeon and can't wait until all is revealed in a future book. I'm of a mind that Sandor is *not* dead and will still get to be the one who kills his brother. The guy on the island was too brisk about claiming that the hound is dead and should be allowed to rest in peace. The guy himself spoke of how he died in combat and woke on that island and now serves there, I think our good buddy the hound lives and is on the island now as well. I just can't let him go like that.
Where's the blackfish going to or is he still in Riverrun? Could be heading to the Vale or just hiding out somewhere, I don't think he has many other options. Speaking of Riverrun, will they ever fix the typo on the map in the front/back of the books? Riverrrun. Grrr
Dorne. Uneventful (well, things happened, just in the end most of what happened didn't amount to much) for most of the book except for showing how bloodthirsty most of them are for revenge, and then finally learning that the prince wasn't just resting on his laurels. Can't wait to see them bust into action when Dany comes to Westeros.
So much was going on with the whole book, hard to keep it all in mind. Can't wait for Dance and especially can't wait for the next chronological book to get released.
