I've been thinking about this for a few days and I feel like the way the Charr society is structured, they NEED an enemy to focus on. In Guild Wars 1 it was the humans, now it's the dragons, but who will it be when the dragons are no longer a threat? Will Charr again become hostile and seek to expand their territory? Bangar Ruinbringer going after Jormag is merely the most recent example of this and he probably felt the Charr needed a common foe in order to promote cohesion among Charr society and to allow him to gain more influence among the Charr. The only way I don't see the Charr becoming hostile again once the threat of the dragons is gone is if their society goes through some radical changes, like how the Olmakhan have a completely different societal structure and now seem fairly peaceful. I would love to hear everyone's thoughts on this.
