  • Ward the flankvision is what turns its best opening into a worse one

  • Respect the spikeRiot rates the kit 7/10, so a practised player gets more out of it than the average

Methodology

Data window
512,340 games on patch 26.16, Ranked Solo/Duo, NA. Last refreshed 20 Aug 2026.
Rank aggregation
Emerald+ and above, pooled. Splitting further leaves samples too small to separate a real effect from noise.
Role assignment
A champion is filed under the lanes it actually plays, not the one class it belongs to — which is why several appear in two.
Counters
A matchup, not a tier gap: how this champion does into that one specifically, over that pairing’s own games.
Minimum sample
The confidence indicator beside every rate is driven by how much of the window this champion appears in. A low reading means read the figure loosely, not that it is wrong.
Why a build is not a cause
The best-scoring build is the one the best-placed players happened to take. Correlation is what a rate can show; it is not evidence that buying those items caused the wins.
Where the numbers come from
Names, classes, lanes, abilities, items and runes are Riot Data Dragon. Win, pick and ban rates are derived samples — Riot publishes none of them, and nothing on this page presents one as measured.
