What exactly as the idea behind stealth change?
I'm not complaining i'm just legitimately curious why they did this? People were complaining about stealth being too strong ever since the vision changes and that there was very little counterplay (when in fact pink wards stopped most of the stealth abusers easily) So why remove pink wards ability to counter it? It seems like it does the opposite of what you would want in a healthy game.
Not being able to set a pink to attack akali/shaco/kha etc. makes them all seem a bit too strong where they would normally be perfectly fine. I know sweeper exist but it only shows you where they are going doesn't allow you to attack
