Last reported sub numbers are 1.6 million (about one month ago). Most people play the game for free using in game gold, so the amount of PAYING subs are much lower.
This is not correct. Every token that gets bought with gold exists because it was created by someone paying real money to Blizzard. Tokens cannot exist without being created in this way, therefor the "PAYING subs" are all the same, as spending gold for game time is really spending gold to buy game time from someone else who paid real $ for it.
This is pretty basic stuff.
