That wasn't the most fun thing I've done in Guild Wars 2. When I went into melee range of the queen, I suddenly took a crap load of damage. Rolled out and was then ran over by a Vet Karka. Seemed like there were more people than a WvW zerg, so the Queen loaded in reeeeally slow.
Not sure what to think about the Dragonstuff, if its anything like the Southsun rare stuff, then I don't expect to get any of the new skins via RNG luck.
I'm guessing it will be like the SAB stuff. Fully farmable if you want to get lots of skins.
