WOW: Win Tol Barad without Joining the Battle

Tol Barad is a ravaged island kingdom in Baradin Bay, between Hasic and the shores of Khaz Modan. The Tol Barad zone plays out like Wintergrasp. There are seven discrete points of interest, with Baradin Hold at the center of the island and three destroyable towers and three capturable buildings surrounding it. If you run across the bridge from the peninsula right before the battle ends you can still get credit for a win without having to join the battle.
