Why would you concern yourself if someone's actually no-lifing? Perhaps,they are far more inferior here unlike on Nostalrius PvP where they were literally sitting on your corpse for 4 straight hours & yet managed to kill Ragnaros within 15 days.
That kill was a BOOM on the server,and the fact they somehow intolerable exploited Ragnaros granted them as the "worst & most toxic" guild that has ever played on a private server.
I am encouraging their intentions & will to literally kill the whole server because to me that's some kind of a task,initially for the gamemasters & secondly for the players in order to slow down their path to achieving what they have previously planned.
