Would it be asking too much to give Lux movespeed when using her W?

What I'd want is when you aim it directly over an ally, it will curve to try and follow them to a small degree.

I mean, I don't know how, but am absolutely terrible at hitting my ally with that. I can hit enemies with skillshots just fine, but allies move differently in relation to you than an enemy will. I just suck at it...

But she's already really strong against melee champions though :s. And her mana costs aren't bad and she has a fairly easy skillshot to hit to bind and an easier E, and she has good scalings ;s. Honestly, she's fine where she is. I'm already annoyed when she can shield for like 500 damage at level 10.
