Listen to me people, Blizzard is a business. As such their only concern is to make money. NO successful business is going to willfully do anything to hurt their goal (to make money) because they are "lazy". I'm pretty sure they know what type of hardware their subscribers use (omg wow is sypware wtf!). Since Blizzard seems to me to be a fairly successful business I think they know what is best for everyone as whole when they decide not to support a dead platform.
"But Slybo! what about whats best for me personally and my dead platform dont I deserve WahhWahhhWahhhWahhh......."
