Haha, yeah one good flash will bring her damage down to zero, so this is why she needs a proper team for her in teamfights...

I used to go Lich bane on Lux, but after I figured out how risky it was to get close enough to autoattack, I no longer equipped it on her. I think the same goes with MF, but in a little bit better situation thanks to Strut and Make It Rain's slow for kiting.

However, you can stack Impure shots really fast with W-AA-Q-AA-AA, but it requires you to put yourself in danger. It's a nice addition regardless.
