Guy has literally >3000 Arcane crystals that are obtained via the layering exploit. See here: Should this be bannable?
The layering exploit allows you to spawn the exact same node, right in front of you, over and over, instantly. You can literally click to harvest the node, swap layers in seconds, and immediately click to harvest it again. For hours and hours and hours.
I saw somebody with nearly 1000 Black Lotus. If you didn’t know, these things are absolutely gold. At this point I don’t doubt people have ~1 million gold worth of items due to these exploits.
EDIT! I’VE JUST BEEN TOLD HOW TO DETERMINE YOUR LAYER AND SWAP AUTOMATICALLY!!!
I’ve been told that the method to determine your unique layer has now been figured out, and boy oh boy, it is easy!
That’s it - Classic is in big trouble. Blizzard needs to fix this asap!
