You cannot go by the petition as its mostly only forum users and if the numbers that keep popping up are to be believed that most of the APAC region!
Nothing like alienating a whole region, better than a nuke...
And of those 800 that signed that petition, how many of them are going to stay subbed and continue playing on the Harbringer/Bastion? :P
Closing APAC is only going to have a miniscule impact on their subscriber base, while saving a lot in costs. Smart business decision. Given the bad state of the company, I don't blame them.
