Riot, Item Sets in the new client, PLEASE.

Why would you remove item sets? Its SO useful for every skill level of player. Even if you're challenger it saves you precious seconds to have a custom item set instead of having to navigate the shop for what you need. It allows new players to benefit from their more experienced friends too. I have played since 2009 and ever since Item Sets became a thing I was able to help out all my friends newer to the game easily and in a way that didnt take up 30 minutes of my time a go.

Can we please get item sets back? I want to use the new client but the lack of item sets is, frankly, disgusting.
