I've seen some mage types all lined up in two neat rows right outside Sastasha (while unlocking it on an alt). THey sorta twitched and then poofed into the dungeon.

Recently I've been seeing DoH bots hanging out between Bentbranch and Little Solace. Some of them were stuck at the sylph NPCs >_> Halp! Botting ones are squatting these ones village!
