League of Legends answers the custom item sets request with patch
League of Legends has introduced the custom item set feature. These sets are pretty much exactly what they sound like. Through the summoner profile of PvP.net, you can set up item load outs to appear in game under a new tab in the item shop. Do you not like the recommended items? Would you rather build up your own load out? Now's the time.
This feature has been requested by the community for some time now and is finally in the live game. No longer do you have to spend a second longer than you want to in the item shop. You know how you play and what you want – now it’s all there for you. You can customize these sets for specific maps, specific characters, whatever your little heart desires.
As of now, the custom saves are only on your local computers. The future will bring server side access; just you wait.
