See here: Player proves you can determine your layer with /who (proof inside) - #156 by Startuptim-sulfuras
As of today, the ability to detect your layer using /who -z “Some zone name” has been hotfixed by Blizzard.
This technique has widely been used to determine which layer you are on as well as used by addons that automate layer switching.
WHAT WAS CHANGED:
The old, pre-hotfixed method would allow you to do the following 2 commands:
- /who -z “Orgrimmar” 1
- /who “Orgrimmar” 1
These 2 commands would show you the specific people in YOUR LAYER, as well as the specific people in ALL LAYERS. You could then use this information to determine which layer you were in as well as communicate this information (via an addon) with others to determine exactly WHICH layer a person was in. You can see many, many examples of this as proof in the above linked post.
WHAT IS NEW:
The hotfix made it so the commands now show the SAME information, thus removing the ability to detect your layer.
WHY THIS MATTERS:
This matters because Blizzard previously stated that detecting your layers was not possible, despite being provided with ample proof. This allowed layering exploits to continue for a large period of time.
Zoom ahead many days, Blizzard has hotfixed this without acknowledging that their understanding of layering exploits was flawed and it allowed exploits to continue more than it should have.
WHAT THE COMMUNITY WANTS:
-
Acknowledge directly that layering exploits are not the intended functions of layers and, as with all exploits, is against the rules of the game and can result in the same actions as violating other rules of the game (suspensions, bans).
-
To reverse all gains made with layering exploits.
-
To suspend/ban those who have gratuitously exploited this flaw for personal gain. This includes popular streamers who provide Blizzard with an immensely valuable free advertising by streaming WoW Classic.
Thanks!
