I wonder why she never buys Blade of the Ruined King. On paper it's perfect for her - % current hp damage makes her % missing hp passive hit harder, the on-hit works with Guinsoo and Runaan, which are her core items. It gives her sustain to survive the laning phase and a little bit of attack speed and damage she needs.

I guess it's just that Stormrazor gives more of those stats.
