LF mid and jg silver/gold

Tired of winning lane losing game. i win lane pretty much every game and get first blood which i guess makes people lazy. last 2 games had bot lane go 1/11 (both adc and supp) 10 mintues into the game. Last game had 4 man ganks three times 10 minutes into the game. Just Lf people that can carry their own weight and back up for the 3/4 man ganks/tower dives. "Just ward" doesnt help when they tower dive you and you just sit there freezing lane saying "I pinged". Why not just follow lane?
