GoT was definitely a story spanning multiple kingdoms within the Seven Kingdoms / HotD just feels stifled by being situated on two tiny islands (Dragonstone, Driftmark) for so much of its storytelling. In my watch I think Allicent goaded Aegon into battle by belittling him ... after he diminished her - and that is an odd but captivating issue I got bored with Daemon's scenes. Visions are not interesting - that his change of mind came from a vision is a big let down that doesn't really justify what we see from character alone
