Farsight Alteration is broken

You're essentially given a free pink ward minus stealth detection every 60 to limitlessly scatter throughout the map without even having to so much as get remotely close to what you're checking. Once this item hits pro games I'm almost certain this item is going to be horribly abused by mid laners that can cover every single jungle/river brush without even leaving their lane. Sure, it dies in one hit, but by the time someone manages to destroy it, they've already been spotted.
