What is kind of amusing is a couple things. So they teleport from NPC to NPC. Some NPCs their name will hover at ground level. But some NPC interactions will pull them up like you see. A good location for watching these bots is by the sylph dailies their is multiple run back and forth talking to NPC. If you lock on you won't lose the lock it slides across.

The other interesting thing is the people who use the excuse we need gated content because it stops bots. They can finish crappy MSQs faster then any regular player. They have no tedium of travel for fetching or talk to NPC only to come right back.

I would be curious to see how it works inside a dungeon for a quest. Do they even have to acknowledge the bosses or can they just go to the end. Is that why some dungeons aren't about kill but travel to X spot. Not that makes much diff it is one more teleport.
