Man, if winning lane were close to winning game, I'd be challenger by now.
That aside, I'm confused.
How are you warding your jungle, your lane, and the enemy jungle with a trinket?
How are you reliably winning lane at your elo without setting up opportunities to pounce on (that the enemy team doesn't have)? I can see going 50/50 in lane this way, but winning the majority of the time?
Unless you're playing below your elo. In which case, sure. But then, how is that advice useful to anyone that wants to climb?
I'll be blunt. It doesn't sound like you understand what a sightstone is for. It's not just for warding your flanks. It's for setting up plays. Furthermore, it sounds like you're regularly playing in really low elo. And if that's the case, have you considered that maybe there is a reason for that?
