One potential 'paygate' down. While I would be happier if this incentive were removed completely (I don't feel the increase in pre-launch sales is worth the decrease post-launch, even in the short term), I am at least happy that 'faction unlocks' won't be for sale.
...unless, of course, they separate all the other goodies (treasure maps, pet etc) and claim that it's no longer an 'Explorer's Pack'. Feel free to rage the internet off its hinges if they try that stunt.
