ashe passive. something new and unique

wanted to put my idea up for the new ashe passive.

maybe op but here it goes

"ashe gains permenant sight of last enemy champion she basic attacks."

cool idea i think especially with a global ult.

obviously is op but maybe

"if enemy champion enters th range of an enemy turret the passive is negated"

anyways just looking for cool passives. gold gains and extra ms/as isnt any fun imo

oh i guess maybe a limited TRUE sight for maybe like 10 seconds after hitting with basic attack. scaling?

how about a passive that deals with mana issues

maybe a built in essence reaver without life steal

anyways hope to hear from someone :)
