Since we've lost the ability to create custom item sets, you at Riot really need to step your game up on the recommended items.
First off, please add control wards into every recommended set.
Second, you're going to have to pay attention to new builds and such as they pop up.
Third, you really have to bring **all** the sets up to date.
Fourth, you are going to have to make quick adjustments as items and champions change.
