About Warding Items

So almost everyone knows what Trinket does, but what if we replace the Yellow Trinket with a New Version of Sighstone?

Example: Each 2-3 mins the New Trinket Version Derivated From Sighstone could earn a Free ward which can be used / stored to a maximun cap of 2/3 (similar to Normal sighstone) and upon upgrading the said New trinket version the cap could increase to 3 wards? or win X more vision.

Just my 2 cents since almost every game none except the suport bothers to buy wards yet the teams fail to realize that there is a limit cap for wards to be placed per player :(.

Oh yes and maybe the free wards from the new trinket could last only 1m and 30 secs? just my 2 cents as i said. discuss please :)
