Do hunters have a blink ability like the Warlocks do? If so, is that what the super jump is? because there are multiple videos of hunters teleporting, but also warlocks. Under the warlock skill tree Blink is an unlockable ability while hunter's abilities are just triple and super jumps.
Thus far we've only been able to see one subclass, there may be other movement modes for different hunter subclasses. Or that could just be the hunters jump animation for either the third jump or the super.
