Your vision score is 0.00 per minute; Silver players average 0.70. 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 take part in 28% of your team's kills; Silver players average 52%. After your first item, look to rotate for dragon, grubs and herald, and keep Teleport for fights rather than for farming.
You spend 65% 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.
