First question is, why are these people permitted to exist? I play on the sieghardt server, and there is a clan that is built specifically for farming raid bosses. I don't know what country they are from or anything like that but they don't talk to people and act as if they were bots.
My second question is, is every server having this now, or is it just sieghardt?
Actually, creating clan with sole purpose to kill bosses is not illegal <.< now if the drop are being sold for real money (which more often than not is the case) it's different. But prove someone's selling something for real money... good luck :/
There are some on Devianne, too. I saw at least one automated group a few days ago take out a Raid Boss. There were so many of them that I almost felt like assisting the Raid Boss. It was over in less than 60 seconds.
