That's probably one of the things I liked most about the game. The sense that, really, you're barely on the periphery of all of these important events, and you're totally irrelevant to their resolution or progress.
It's not that Geralt is irrelevant. Indeed, everyone wants Geralt's help; Radovid and Emhyr, but also Roche, Thaler and Dijkstra. They know that having this superhuman warrior and tracker that knows every important person from Kaer Morhen to the city of Nilfgaard on your side is a good thing to have.
My beef is that almost all related to the war happens in side-quests, where Geralt just pops up, does something important, then goes away and the consequences of his momentous actions are barely given any focus. Reason of State is the epitome of this;
I'd have thus rather the Novigrad arc(s) focus more on the war, rather than tracking down Dandelion, finding Sigi's treasure, and dealing with the most boring antagonist in the game (Whoreson). The Skellige arc worked as an adventure with Yen, the Kaer Morhen arc brough out all the feels between laughter and tears, and the Velen arc is the best part of the game which is really saying something. Yet everything that happens in Novigrad just feels lacking compared to the rest. Reason of State is just the most prominent example of how weaker the narrative is there. Cripes, I felt more investment in High Stakes, and that quest was about a freaking card game tournament!
