Yellow Trinket needs a buff or bring back wards.
Early on in game having to wait usually a full 1-2 minutes after using all your available charges before you can get vision again or having to spend gold on a pink ward that will most likely die shortly after it's placed and that's wasted gold.
Also playing jungle, I feel like I have to buy a Sightstone just so I can keep my jungle actually warded and visible. Some games I face a shaco and you know Shaco's annoying as hell in your jungle and I simply can't keep track because I place one ward down some where, wait 30-40 seconds, place the second charge down, then wait a good 2-3 minutes before I get more charges. Laners can't really come in and ward because they've already used their wards or they're too busy farming and poking or just have no map awareness(usually the case everybody in my MMR doesn't watch the map for shit lol.)
I feel fine playing support because Sighstone serves a good, useful purpose for a support and doesn't take any space up. But on junglers a Sighstone is gold that could of been better spent.
if you are jungling if you are having issues keeping your jungle warding. I always get this item to get vision in my jungle.
