Duke Ravenclaw #NA1

You take part in 43% of your team's kills; Gold players average 53%. After your first item, look to rotate for dragon, grubs and herald, and keep Teleport for fights rather than for farming.

You spend 54% 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 50% 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.
