Your vision score is 0.45 per minute; Platinum players average 0.90. 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 33% of your team's kills; Platinum players average 55%. After your first item, look to rotate for dragon, grubs and herald, and keep Teleport for fights rather than for farming.
You spend 16% 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.
Your main role is only 20% 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.
