Normally my clan finds things out such as exploits and what not, just like the many out there.
the other day on Molten MoP realm, I was just lurking around Orgrimmar, where the high levels duel.
This one Panda (he came out of orgrimmar to the entrance) asked a Mage for a portal to Undercity, usually it is rare for some random Panda to ask for a portal, when Orgrimmar and the rest of the Barrens is there.
The Mage accepted and made a portal for this Horde Panda. The Mage continued to say WTF and the Panda told the Mage he is in a raid.
That Mage said to the Panda that how is he teamed up with Alliance and Horde players at the same time, the Panda told the Mage, that he is going to help out his friends, needing to go anywhere within the Eastern Kingdom as soon as possible.
The Mage ended the conversation with only GMs can team up with any faction, and told the Panda good luck and the Panda took his leave to Undercity.
I spoke to the Mage about what the convo was about, he ended up saying he spoke with a few Alliance players while he was temporarily in that group then he went off to BG.
To me, this strikes as bizarre, especially on Molten, for I never heard of such at all. There is only one guild server-wide that is capable of adding members of any faction and that is The Molten Staff guild obviously. I told members of my clan about it, they didn't know either, hell even the leader himself, however, they remain on the Cata realms so they do not know MoP as much.
I looked at DS (not gonna mention full name) there is nothing on this issue and I am certain Jackyn, Broly and the others I know who are knowledgeable about hacks/exploits do not know this as well, I'm surprised Hive doesn't know, even though he remains on Cata.
So as the question is: How the flying fudge did this guy managed to have Alliance and Horde players in one raid group, and are able to communicate (then again, I think MoPs language barrier is broken) with each other?
EDIT:
This guy is nowhere to be found, he was a low level horde, level 19, at the time I did a /who, there were a few level 19 pandas in the silverpine/hillsbrad area.
Trying to figure this out still, if not, then another trick to be learned for another day.
