Yo Yosh, Can you please disable the ability to teleport?

[ErBear]

You enter Frontlines from the airship counter in the city-states.

You queue up for guildhests by talking to battlewarden NPCs in many aetheryte camps and/or hamlets. And while guildhests are instanced, they are instanced sections of the open world (something that was done extensively in 1.0 if you recall).

Yes but there is no actual area on the map for guildhests, unlike the dungeons where it's kind of a physical place that you can travel to, you can't travel to frontlines nor guildhests, it just teleports you to some random area, that can't be seen.
