If I'm in a party with a friend who is also a herber I HoP then on my paladin and take the node
If its someone fighting near a node, I help them kill the mob, if they take the node, thats fair play, if they don't and move on I will herb the node
Usually if its me fighting a mob near a node I want, I usually drop conc on the mob so no one from the other side can take it from me while I'm fighting, though it doesn't stop fellow hordies for doing so, which is rather uncool
