November 4th PvP event

I just wanted to make the discussion about the Tarren Mill vs Southshore brawl. Its a well known fact alliance outnumber us by a lot on Nethergarde, so it will probably be something like 5 to 1 on that event. Think it will be fair if horde players get some kind of buff like Tenacity in Wintergrasp? Otherwise it will be pointless, we will just get overrun.
