One of the core conceit of GOT starting out (books and show alike) was that the petty political squabbles of the powers that be would be fundamentally irrelevant to the looming threat of global climate change, but both the show and the books became enarmored with heroes and villains, and the interpersonal drama of the setting's political intrigue, effectively pitting the (interesting, fun to watch/read) political drama against the magic climate change plot. There was, in my opinion, no way to resolve this fundamental contradiction within the series in a satisfying way.
Not just your opinion.
