Like in San Andreas when your hoods were being taken over and you could go defend your territory?
Exactly. That was annoying. The system should be that it either happens in front of you, you walk into the town on hte tail end of the attack, or you walk in to see the devestation.
That would be a great way to be introduced to dragons attacking towns - perhaps like a scripted quest, where you travel somewhere for something and find the town on fire and destroyed, and the scale of destruction is just like "Wow ... what could have done this". Buit later you are introduced to live dragon town attacks .... if that makes sense.
