When browsing the different sites and tools made from the community, we have all heard at least once that X champion counters Y champion,
but as a lot of people with a scientific background, we like to get the truth from numbers.
Thus we made LolDuel, which is a webapp we built to calculate what the actual winrate stats for champion matchups are.
Our site is pretty simple since we have only one clear purpose:
we crawl plat+ ranked games everyday and parse the data to make our calculations and display them to the user.
