Your vision score is 1.69 per minute; Challenger players average 2.10. 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 50% of your team's kills; Challenger players average 62%. After your first item, look to rotate for dragon, grubs and herald, and keep Teleport for fights rather than for farming.
Your main role is only 55% 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.
