Many years ago, I ran a packet sniffer on EQ using a 2nd computer on my network. It would map out the zones, NPCs, zone spawns, etc. It was never detectable by Sony unless they actually scanned my network. No information was sent to Sony, it only read the incoming packets.
I've searched the forums for one that does the same thing, but have been unable to find what I'm looking for. Does anyone know if a program such as this exists for WoW?
I've seen other sniffers posted but they don't seem to do anything worthwhile.
