About the League Randomizer
Randomize League of Legends champions with a role filter. You can select multiple roles at once, or just one (the choice is yours). You can also randomize the skin for individual champions. The roles assigned to each champion are based on this list. It combines data straight from the game client, as well as those statistically determined by third party analytics services. It is also possible to include/exclude champions from the pool (your browser will remember your selection) to customize your randomization further.
I don't intend for this page to be wildely used, it was made on a request from a friend and I saw it as a great opportunity to challenge myself to make a simple web app. New champions are added to the pool manually(because of the custom role assignment), but skins/images stays up-to-date automatically since they are fetched directly from the League API.
