A node is a point of interaction. Specifically, a node may refer to a vertex on a graph, like a destination on a flight path map. A node can also refer to a resource node, such as the five found in Arathi Basin. Resource nodes may also refer to the placen where herbs, mining nodes, fishing pools or gas clouds spawn, or to the herbs, mining nodes, pools or clouds themselves. Cobalt Deposits were known as Cobalt Nodes during the Wrath of the Lich King beta. Generally, a node can be any point at which entities spawn, like graveyards or starting locations in battlegrounds.
