Here's what I wrote in my diary thread about the war table. It's an authentic reaction since it was written during my first playthrough just a few days after DAI came out:
"Before I forget it again, I have to mention how the war table operations enhance the way you feel you impact the world. Often, their outcomes vary depending on which advisor you choose for them, and that means how you roleplay these choices affects the world. It's actually sometimes more convincing than missions you attend to in person, where there is, sometimes, still the impression you get your say and the story continues on its predetermined path, leaving you no real impact. I suspect war table operations are easier to make in this way because no cinematic scenes and no dialogue is required, and because they're of a smaller scope so that you can write their consequences into the story without having to address them in future games. Anway, the result is that the war table feels like the primary way I impact the world as the leader of the Inquisition, while the roleplaying opportunities in the quests serve more to flesh out my character but apart from the plot forks where I make major decisions, have no impact on the world. This combination works surprisingly well."
I still think the same about it. it may be DAI's best new feature.
