In World PVP, Druids are among the best and have a number of advantages. Like Rogues, they are able to stealth, and like Hunters, they can Track Humanoids. This allows them to sneakily stalk and ambush enemy players with the enemies being none the wiser. Due to this, Druids are nine times out of ten able to attack first when in World PVP.
For Balance Druids, Entangling Roots and a devastating barrage of damage spells can route any unsuspecting enemy as easily as if they were NPCs. Faerie Fire can deny any Rogues from Vanishing and in turn stalking the Druid. In addition to this, if anything goes wrong for the Druid, they are able to escape situations with extreme ease due to their Shapeshifting, high movement speed and stealth abilities.
