So in looking it up, it does not specify if you are alliance if I can engage them as horde, but I assume since they spawn in the faction camps, that you cannot easily try this on the other faction, as you will get attacked. Also, since the location is in the phased area of Krasarang, that you can only access at 90, and you are doing it alliance side, I will not be able to attend. I have one level 80 alliance toon, and the rest are horde at 90.
Thanks for the offer, though. I will keep my eye out now, for someone doing this horde side, or get off my bum, and get a crate myself.
