Item Sets

So I know Rito aren't putting the item set feature in the new client but I think there was some use in it. In the legacy client I thought the item set system had a pretty clunky interface and had thought there must be a better way to implement this useful feature (especially for champs with flex roles. Kench and Nautilus have support recommended builds for example). I wonder if Riot could take the opportunity of client updates to implement an in game drag and drop item set in game allowing players to plan a build tailored for the opposition instead of spamming control 4 while confined in base. For less experienced players, or ones who are slow shop searchers, a more dynamic drag and drop system could level the playing field and allow players to consider their builds in advance. Thoughts?
