Your vision score is 0.00 per minute; Emerald players average 1.00. 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; Emerald players average 56%. After your first item, look to rotate for dragon, grubs and herald, and keep Teleport for fights rather than for farming.
You played 13 different champions in your last 13 games. Consistency comes from mastery: pick two or three champions for your main role and play them until the mechanics are automatic.
You spend 90% 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.
