HOLY ****. Great episode.
The riot at King's Landing was the best part personally, with Theon killing Cassel not far behind. Also loved the "Oh crap" moment when Littlefinger entered Tywin's solar with Arya in his presence.
Those changes, on the other hand. Eh, if the writers can find a way around them, it'd be fine.
