You actually see more then ?? That's shocking...

"Upgrade causes damage amplification for 5 seconds"
 * An easier way to do this would be to have the lingering vision decrease armor and magic resist by xx amount.

But I agree with some of the things below.

Giving it a visual ping on the mini map would be helpful.

And let it give assists when it reveals a person. Exhaust, Heal and Clarity do, why not Clairvoyance? Is being able to see a champion in the brush not assisting the team to kill that champion? And that way you get some bonus gold for using it properly, as you are already starved of gold in the support role.
