I always felt that one of the main problems with GoT/ASOIAF was that it was a nuanced, political fantasy with top class world-building, but the overarching plot was pushing everyone towards a massive final confrontation (or 2 really). There was not really a good way to resolve the confrontation without a massive battle (or 2). So the ending was always going to have to move away from what made the series interesting/successful (book and TV), i.e. plot, characters, intrigue, shades of grey.

There were other problems as well, but that was something baked into the whole series by GRRM, and I’m not sure he can really find a way to do it differently. He might come up with a different outcome of the final confrontations, but it still has to be done with epic battles.
