Why did we ruin yellow trinket?

Don't get me wrong, I really like blue trinket, but the new yellow trinket is garbage in comparison to the old upgraded yellow trinket.

Here's my proof too, cause apparently taking things for face value isn't enough.

Current Warding Totem; Places an invisible Stealth Ward which reveals the surrounding area for 60 - 120 (based on level) seconds. Stores one charge every 180 - 90 (based on level) seconds, up to 2 maximum charges.

Previous upgraded Warding Totem; Places a Stealth Ward that lasts 180 seconds (60 second cooldown). Store a charge every 60 seconds, up to 2 total.

So it was in every way better. With it, you could actually ward your lane at least semi-efficiently. If we reintroduced this, then the blue trinket would actually have a competitor as far as trinket choices go.

So hows about we bring this epic trinket back? (Especially since they removed stealth wards.)
