If they intended the ban to be similar to SoD’s ban then yes it does include buying dungeon loot.
So everyone in a GDKP magically teleports to the boss and it just dies? There is effort put forth, that is a crazy argument to try and stand on.
That being said, Blizzard is doing absolutely nothing to stop people from breaking these rules.
Maybe they’re making a big list and they’re going to ban everyone in waves?
