Wow has a lot asian customers and especially the chinese ones pay “only” 7cent/hour
That’s regional pricing for you.

Weren’t Asian users more relying on Cyber-Cafes for their internet gaming? The pricing scheme might be drastically different.
Well in china you buy WoW gamecards with either 4000 or 2000 mins and the client is entirely free. The internet cafes dont make a difference, because you still have to use your own account, you only pay for the usage of the computers/hardware. Many chinese gamers dont have a own pc. So the pricing scheme shouldnt be affected.
Oh. I mentioned it because people I know who were into the Cyber-Cafe business (When it still was viable here in Spain) who had to actually negotiate with game publishers for special licenses (and thus cannot hear the name EA without bursting into angry fits), and from what they told me, Blizzard had special dealings with Korean cyber-cafes to accomodate their business model…
But, in any case, second hand information from a few years back about a different continent, probably not that relevant. :
