Frequently Asked Questions
Short, honest answers about how the site works.
Where does the data come from?
Everything comes from the official Riot Games API — matches, ranked entries, summoner profiles. Champion, item and rune icons come from Riot’s Data Dragon CDN. We don’t scrape other stats sites.
How often is the data updated?
Global counters and tier snapshots refresh roughly every 30 minutes. Individual summoner profiles refetch on demand when you open them, and match history updates as new games are played.
How are tiers (S+ → D) calculated?
We compute z-scores over each champion’s win rate, pick rate and ban rate across the current sample, then bucket them into tiers. That means tier placement depends on how a champion performs relative to the rest of the roster — not on hand-picked opinions. See the full write-up in How our tier system works.
Why does a champion have a different tier here than on other sites?
Different sites use different sample sizes, patch windows, rank filters and formulas. A champion that’s S+ in high-elo only might be B overall. Bigger sites also have larger samples, which changes the z-scores.
What is the Playstyle Radar?
It’s a six-axis chart (Aggression, Vision, Objective, Survival, Farming, Teamplay) that compares your averages to the other 9 players in the same games. See Reading the Playstyle Radar for what each axis means.
Why can't I find my account?
You have to have played at least one match that our ingester has seen. Try searching by Name#TAG and pick your region. If it still doesn’t show, open any recent match on a friend’s profile and click your name — that forces a refresh.
Can I remove my profile from the site?
Yes. Email contact@bestbuilds.lol from an address you can prove ownership of, or with your Riot ID in the body. Match data attributed to your PUUID will be suppressed. See the Privacy Policy for details.
Which servers can I look up?
Every live League server: EUW, EUNE, NA, KR, BR, LAN, LAS, OCE, TR, RU, JP, PH, SG, TH, TW and VN. Ranked, normals, ARAM and clash matches are all ingested the same way, so anything you queue for shows up on your profile.
Is it free? Are there ads?
Free, no paid tiers, all stats unlocked. Ads keep the servers running. Personalised ads only if you consent, and you can change that any time from the consent panel that pops up on your first visit.
Is this affiliated with Riot Games?
No. BestBuilds.LOL is an independent fan project. League of Legends and Riot Games are trademarks of Riot Games, Inc.
