Lissandra E idea

Thought this would be an interesting mechanic, if you hold down E, the claw will go in a line, but if you tap E it becomes a damaging blink wherever it is cast with less damage. Thoughts?

To clarify, the blink would be the same animation as the claw coming down at the end of the path wherever it is cast. I think it would be interesting. Although not a popular champ lissandra always has a special place in my heart.
