Team synergy in my opinion is the next levels that ugn should spend some time looking into ( which champs complement each other) That also goes hand in hand with what role you are able to perform well in as well as which way to build that champ not only for yourself but for the eventual team fight synergy . Just my opinion
Do people build their item sets for a specific champ or do they build a generic adc, jungle, apc, etc?
I think you guys are forgetting that Kirks is asking from a complete noobie perspective.
