Some aspects of battles are in fact very well done, The assault on Adamant Keep is maybe the best sequence of warfare I have seen in a DA game. Good buildup,war table discussion, intro scene, action, etc. It had all the elements. Very well done.
Haven's destruction was also fairly well done, with those waves of enemies assaulting.
What is lacking however, is maintaining that level of threat through the zones. In the Hissing Wastes, those small camps of Venatori and Red Templars (usually just over the hill from camp - for farming perhaps?) had no organization associated with it. Always just three of the enemy... except the camp on the top of the hill. I would like to see a quest to assault a major red Templar/Venatori camp somewhere, with similar drama associated.
What I believe the thread started out about though is the absence of the effects of war on the country - no widows, orphans, etc. Or maybe not
And it is strange that after that attack on Haven, that the red Templars just stop hunting you. Why? I would have expected a few concerted attacks on my party in some areas, as it would have strengthened the story and immersion. Remember those random darkspawn attacks on the road during DA:O? They made the threat more 'real'. The darspawn never just went away, like the enemies in DA:I seem to do, unless YOU attack them.
They SHOULD be attacking me, hunting me, in the name of Corypheus. Otherwise it feels like he is just ignoring you, awaiting his fate
