Similar to how the champion selection works (sorting heroes by mage, disabler, etc), it would be nice to have the item shop built the same way. For example, selecting "Spell Damage" and "Movement" will show the Sorcerer's Shoes. This way people can get exactly what they are looking for when they are optimizing builds.
Over where it usually says "Recommended Items", you could put a feature where someone can just select a build they are already planning on using. Examples would be "warwick jungling build", "warwick end game", "teemo AP build". This will make it easier for people to get to the items they want and try out new builds/strats. The recommended build for that character will still be included and set as the default selection at the beginning of the game.
Also, I just changed the item description so it's slightly easier to read. It's not that big of a deal but I thought I would just include one last thing.
