I agree that it’s not game breaking, that’s not what you said. You said it was proven to not be an exploit when what Blizzard said (and what you quoted) clearly showed that they do view it as an exploit. An exploit is still an exploit even if it doesn’t cause serious harm to the server. Arguably most exploits aren’t going to significantly affect the game.

The ability to teleport and jump to different layers using a 3rd-party addon specifically designed to scan layers and avoid previously visited layers in order to farm rare nodes/spawn points is:
You are delusional about what is now deemed by Blizzard as an exploit, which they are working on to prevent. But please, go ahead and continue to exploit Classic using your exploit and get your rare nodes. The majority of the Classic Community is loading up their salt-shakers.
