How about a real "STEALTH" ward

Wouldn't it be cool and actually pretty helpful if we had a trinket or a consumable item that we can use like the Farsight Alteration . But the function would be much much different.

Anything in its radius would become invisible unless spotted by true vision or ignite I would exclude Baron, Dragon and Rift Herald in this effect but introduce a way this ward can be helpful for a scenario like that. As stated before anything inside becomes invisible for a few seconds BUT while inside the units are near-sighted.

For those who don't know what near sighted is. It's where eats you or ults or when uses his smokescreen or when uses blinding assault.

I think this mechanic/item would definitely change the game. Bringing massive amounts of diversity. Want to gank but the bush is warded? stealth ward the area so you can get in position! Are you doublelift always overextending? stealth ward yourself or the enemy to buy some time, make a cool a play, or probably waste it! Teamfight in the baron pit with baron PO'd? stealth ward the enemy on the edge of the radius so they can't see jack! (Perfect for a baron steal!).
