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.
the other sub classes haven't been revealed in depth yet - possibly the blade dancer or 3rd trees use blink instead of a double jump.
Each sub-class supposedly has separate supers, grenades and jump types
