Stealth and invisibility need to be fixed

When Riot talks about balancing and making sure there is a proper counter play so there is "balance" i feel they dropped the ball when it comes to stealth and invisibility. sure you get to have sight wards form dropped items like Teemo's mushrooms and Jihn's traps but they do nothing to help you target champs that are invisible, same goes with the sight trinket, whats the use of having it if all you can do is see they guy who is invisible but cant target him. i don't think that its a bad manic to have the ability i just think there needs to be better counter play around it.
