So....uh....stealth counterplay

Can we get vision wards back? I'm really sick of having to ban stealth champs because there is nothing in the game to counter them. Control wards? Nope. Sweeper? Shows a shadow but you still can't target them and you have a better chance of getting mauled by a brown bear and a polar bear in the same day than to guess right with a sweeper. Lens? Same problem. There seriously needs to be some way to counter the stealth. It is way too strong as it is.
