Thats easy, they were created on the realms themself using a prog that just eliminated current runes and kept the stats. IT was made by some newb that couldn't win legitly so they made a hack, thats why msot hacks are made. They cant win and wanna be the best but cant be.
hmm i thought i remember hearing that they were made on open bnet and then brought on to the realms.. i might be wrong tho. where can i find out more about this program that took the runes out of items and kept stats can u give me a link to sommore info.
