Jayce
Figures on this page are from League of Legends patch 16.18.1.
The win, pick, and ban rate figures here are a third-party League of Legends statistics provider's aggregation of match data that originates with Riot Games — Riot doesn't itself publish win-rate statistics. See how it works for the method, including the per-tier noise-width (σ) calibration Should I Dodge publishes on top of that raw data — how far a rate actually sits from meaningless, not something the provider itself measures.
| Role | Win Rate | Pick Rate |
|---|---|---|
| Top | 47.0% | 3.8% |
| Mid | 47.8% | 0.6% |
About 3.0% of games at this tier see Jayce banned before anyone even picks a role — one number for the whole champion, not something that genuinely differs lane to lane. It's shown here alongside Jayce's Top numbers, the highest-pick-rate role, purely because that's the row this page leads with. Why isn't this broken down by role?
Jayce's Top win rate is 3.0 percentage points below an even 50% — Should I Dodge's win-probability model varies by about 4.8 percentage points of standard deviation from lobby to lobby across all ranks, purely from which champions get drawn, so this gap is smaller than that noise, not solid evidence the champion is unusually strong or weak right now.
Jayce is tracked in 2 roles at this tier scope; the per-tier, threat, and counters reporting below all use its highest-pick-rate role, Top — its numbers in Mid (0.6% pick rate) stay visible in the table above but aren't carried into the rest of this page.
Jayce's Top Win Rate By Tier

Jayce's Top win rate ranges from 44.9% at Iron to 49.8% at Grandmaster across the 10 of 10 ranked tiers with published data for this role — a 4.9-point spread. Measured against each tier's own noise floor, that's 0.03σ at Grandmaster and 0.68σ at Iron, with only the Iron figure clearing the 0.5σ bar Should I Dodge itself requires before calling a reading anything but Neutral. See how noise-widths are calculated and what they mean for each rank.
Should I Dodge's curated read has Jayce's power curve as a strong early-game lean — it wants to end the game before it scales away, a community-consensus judgment about where the champion's power peaks, not measured win-rate-by-duration data (the stats source doesn't publish that).
Should I Dodge's curated read flags Jayce's kit as carrying poke — a community-consensus judgment about what the kit threatens, not measured win-rate data, and the same read behind the counter-build suggestions on the analyzer.
Should I Dodge maintains Jayce's scaling lean and kit-threat reads above by hand, one champion at a time, across the whole roster — not generated from the win-rate numbers on this page, and not refreshed automatically when those numbers move.
