Point of information: Mobs do not come with adds because of how hide works. As far as we are aware, hide pulling is not under any sort of GM interdiction.
The TMO VP pull spot is convenient solely as a means to evade VD. Well, and the view I suppose. The optimal pull spot is near Nexona. It's got a convenient zone out nearby, and no nearby mobs.
Also, often times the dragons come via the pathing nodes. Other times, they warp. Warping dragons are actually more dangerous as they pop on top of the tank and can often AE the clerics or get stuck on a pillar. An excellent example of Druushk behaving normally is here:
