Warsong is an original and highly populated US PvP server in the Ruin Battlegroup. It is home to a large international community including players from Brazil, China, France, Russia, and more.
Although the official language is English, if you get into major Horde cities, most you'll see is portuguese, denoting the dominance of Brazilian players.
The server has a somewhat famous reputation for being rumored as being the best PvP server in the past days, and having exceptionally drama-filled forums. A website was previously created to document the most extreme incidents.
