True to form of the chinese gold farmer, these people will do whatever possible to screw you over and take from you.
someone coming up and taking a node from you, ok, that happens and you gotta deal with it.... but people who will aggro far away mobs and then drop that aggro on to you so you cant even attempt to loot anything. that is nonsense and should be considered harassment. And it is exactly what the people of this guild does. They need to go.
