I've just published a new set of improvements to the website.
The Items page has been totally reworked: Instead of seeing a list of "most used items", you now can see what items do the champs buy first, then what are the core items (the first 3 top-level items bought, and the buy order), an the end items. I think this way is far more useful for the player to be able to know what item to buy first.
Then, I also added a new data on the summoner page: afk count ! Now, if you AFK in a RANKED game, your afk counter will be increased, and everyone will be able to see that. The aggregation of data started only a few days ago, so the afk you did before a few days ago will not be taken into account.
I just published a new wave of updates :) Here is the changelog - Portuguese has now been translated - Team profiles: When clicking on a team (or on the summoner league, from the summoner page), you'll see this team profile, its roster and its match history - Masteries: finally, masteries have been added - Some minor bug fixes on some specific browsers!
