Can get make RED TRINKET DO THIS?

Assuming everyone is FULL BUILT ( 6 items ) there is 1 problem in league that is going unaddressed.. and that is how do you deal with STEALTH once you are full built, or have 6 item slots filled up?

Currently the methods in which to deal with stealth and counter vision is solely based on pink wards, but what happens when you have no more room for pink wards?

This allows stealth units like twitch / vayne who both scale well into late game a huge advantage over others with people being unable to counter them or spot them.

I am a twitch main, and i see this all too often with the ease once the 25 minute mark or so passes with which to utterly destroy people.

Upgraded red trinkets NEED to give vision to stealth units around that player... its simply a mechanical issue at this point that unless you have a pink to drop, stealth is uncounterable.

League is all about rock, paper, scissors but playing as vayne / twitch / khazix / rengar / teemo / shaco or anyone else with an ACTIVATED stealth ( ok teemos isnt active, but no one loves him :-D ) it becomes a game of rock, scissors, and no paper.

Another solution would be to bring lightbringer to the rift from ARAM.

Again, as a TWITCH MAIN, STEALTH NEEDS TO BE MORE COUNTERABLE.
