World of Warcraft PvPers, here's a heads up. This year's WoW Arena Tournament is about to begin and the call for combatants has just been released. Yes, Blizzard has just opened registration for the new Arena Tournament.

For those who are interested in registering for a chance to win cash prizes, you'll need to shell out US$ 20. In case you haven't been playing for the past couple of months, the Season 4 Arena Tournament will feature 3v3 competition and will allow participants to create three characters with access to PvP weapons and armor. Also, the tournament will span from March to October and will be held in special realms.

Special rules and restrictions apply (like Canadian residents aren't required to pay the fee, but they are required to write an essay) so it'd be best if you give it a once over. Hop over to the official World of Warcraft Arena Tournament page for more information.
