You'd think, wouldn't you? Then again, the Charr being as generally obsessed with order, efficiency, and pragmatism as they are, there might actually be some regulations as to where, how, and what is used. And that would certainly be interesting to find out!
Of all the content to in GW2, the Charr story and their Black Citadel I'm anticipating the most. The bit's and pieces of it that are revealed in Ghosts of Ascalon
are really interesting. I like how they explain the social hierarchy, the difference between the four legions (blood, ash, iron, flame), and the reasons the Flame legion has been exiled by the other three. They also go into explaining why no one ever saw a female Charr in GW1, and how that's changed Charr society over the last 250 years in Tyria.
besides, humans are SOOOOO GW1, lol.
