Your vision score is 0.71 per minute; Silver players average 1.40. Buy a control ward on every recall (75 gold is the cheapest insurance in the game), use your trinket off cooldown and sweep the river before objectives.
You spend 10% of your games dead. Late deaths cost a minute each; when a fight is lost, back off and defend rather than adding one more death to it.
4 of your last 8 losses ended in a surrender. Comebacks are common at Silver: one Baron throw or a caught carry flips most games. Play them out.
Your main role is only 36% of your games. Each role has different macro; playing one primary and one secondary role gets you a lot more repetitions of the same decisions.
1.6 solo kills per game — you win 1v1s. Use that threat to draw the enemy jungler to your lane and free up the rest of the map.
