Sight Stone Needs To Be More Cost Effective.

I'm a support main and I watch my wards like a hawk, but now that my Sight Stone has 3 charges I can't replace my ward net when it goes down. Before I could place a ward in River, Tri-Brush, and then have a third for either land brush, deep, drag, or the one tuft down by mid (do we have a special name for that one). Now if I do that I can't replace any of my wards when they go down, meaning I either need to back more or stick with yellow trinket cuz it at least recharges in lane and my ADC and I can rotate our wards to have constant vision. It just feels like SS has become a mid to late game item because it almost punishes you for buying it in the lane phase. I know that scanner it important early to help ganks come though but I need to ask whats more important, security or the chance you could get pushed in well enough for a gank. I just want my SS to give me 800GP of value all game not just after the lane is over.
