Pink Ward change to increase strength in a QoL way.

All I want is a pretty minor buff, a change so that Pink Wards are only visible to champion units/other pink wards. This would mean that you actually have to check inside the bush, rather than just ward it at range, or even worse, use an ability which grants vision of an area, to see a pink ward. I would give this pseudo-stealth a 3 second delay to enter, just like normal wards, so that you could potentially notice one right as it is getting placed if you already had vision of the area. This would make them much easier to defend if placed properly or in a fight, and prevent some of the more cheap methods of destroying them that some exetionally long ranged champs can abuse.
