In the lore of Destiny it appears that warlocks are the main class that have blink and also says that some hunter ( bladedancers) have learned blink from warlocks.
So why does only the voidwalker have blink? Stormcaller needs blink too I think

1 ReplyStormcallers appear to have a spinoff version of blink tied into one of their skills, it said that it allows the use of a "teleport" on L3 from what I remember.
