AD fiora with stormraiders surge
actually works pretty good and kindof compensates for that loss on the slow on her e.
due to her high ad values, shes going to deal a good chunk of true damage on her passive. especially her ult. that burst of movement speed + slow resistance from triggering one or two vitals can really give her the ablity to move around and finish her target off by triggering the remaining vitals.
this is the build ive tried on her

only in normals so far, but worked out surprisingly well.

and
if its a heavy ap assassin team
or
depending on the enemy team comp
if a heavy hard cc team
