Erm, i quoted just a handful posts ago, on this same page, a blizz employee who answered someones inquiry to why pandas suddenly lose the ability to speak to both ally and horde. Though it revolves around the singular topic of pandaren, the response would most likely be no different if the topic went to the general topic of cross-faction communicationTeigan wrote:Personally, I wish we could actually speak to the opposing faction. From what I understand there are some MMOs that opposed factions don't have the artificial language barrier we do. Enemies can talk to each other. It just makes more sense that way. Sure it would add some griefing but some understanding as well. As several people have said, the language barrier really doesn't make sense. Why can I talk to a night elf quest giver, but not a night elf? How do the Earthen Ring and Cenarion Circle get anything done if they can't talk to each other? Oh wait...they can. How do alliance pandas suddenly forget the language they've been speaking their whole lives, rendering them unable to talk to my horde panda?

If you google cross-faction communications and check out the threads posted, the general player base that has actively posted and voted in those threads run on pretty much a 8/10 on not desiring cross-faction communications to be lifted. Blizz would probably lose a lot of their base if the active voters in those threads was just a small tip of the overall player base in dis-favor of the idea.
Not trying to bash, sorry that its kinda hammering the subject, but its a reoccurring topic that probably will never have an end but blizz has no intentions to lift the barrier and i've read in one ticket i found on a forum that sneaking around the barrier to talk in understandable words to the opposite faction will and have actions taken against their account for breaking the rule of no cross communicating.
