Wow as a country/product advertising

If u'r playing World of Warcraft (wow) u should know the best guild like Nihilium, Curse or Death n Taxes. They are leader of all PvE content in Wow and some of them got sponser. I know this is typical way to advertising but if ur the best guild ppl will acknowledge you and ur guild coz Wow have 10 mil player now. Its more than some country in the world.

For example. ATI corp wanna use Wow to advertise their product maybe they must get 25 best player with the correct class and name the guild "Powered By ATI" .

hehehe.. the problem is, to be the best is not an easy task. Speaking of myself, our guild only end up in SSC and TK and there's hundreds of guild already farming the last content within this patch (2.3). Maybe if u pay them to play this plan could work. errr let say RM2k per player plus RM60 for reload times 25 player.. fuh..
