Nusibe Necropolis.. broken spawn, possible exploit
When you finish the quest at Nusibe Necropolis and get ported to The Core, there are a bunch of nonaggro level 50 4dot mobs. They are not aggro, are not social and you can basically sit there and experience for hours with no risk. To top it all off, they have a very fast respawn time.
Not sure if the server was all borked up or if it's been fixed, but if not you'd probably want to take a look at it... don't think it's meant to be that way since the giant skeletons upstairs surrounding the Level 60 are also nonaggro but you still need to lul pull and avoid getting near other mobs for fear of social aggro.
Should be looked at... then again this is Vanguard, this might be working exactly as intended.
