Which subclass would you put it on?
Solar - Already has Icarus Dash and is 2nd or 3rd most popular subclass, so doesn't need a buff
Void - Already has Blink
Strand - Has Grapple for moving around, so Blink seems unnecessary
Arc - Melee activates while sliding, so I don't think Blink would help much here. However, if a subclass were to get it, I would think it would be Arc Warlock to match with the other Blink abilities, and it would align with the aggressive playstyle
Stasis - Blink doesn't belong with Stasis. It's supports an entirely different playstyle, and I don't even remotely see the lore working
