This is common in China there are a lot of Raid for cash guilds. They will even run my whole teams through content for gear ect. All i would have to do is stand at the back and let them kill stuff. So far I've not taken them up on the offers beacuse I'm saving for my mounts and my current guild already does ok so I'm already starting to gear up. I guess this is what happens when you dont have the Wotlk expansion yet and most people already have the ubber gear.
