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.

Attack: 5 / 10
Defense: 9 / 10
Magic: 3 / 10
Difficulty: 5 / 10

Riot's own handcrafted 1-10 designer ratings, not measured gameplay stats.

Role	Win Rate	Pick Rate
Top	50.0%	2.5%

About 0.6% of games at this tier see Sion 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 Sion'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?

Sion's Top win rate is 0.0 percentage points above 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.

Sion is tracked in exactly one role at this tier scope, Top — so there's no ambiguity below about which lane the rest of this page's per-tier, threat, and counters reporting describes.

Sion's Top Win Rate By Tier

Tier	Win Rate	Pick Rate	Edge (noise-widths)	Clears 0.5σ?
Iron	49.9%	1.6%	0.01σ	No
Bronze	51.7%	2.0%	0.27σ	No
Silver	50.2%	2.2%	0.04σ	No
Gold	50.4%	2.5%	0.07σ	No
Platinum	50.5%	2.7%	0.10σ	No

Grandmaster	45.8%	2.8%	0.56σ	Yes
Challenger	50.5%	2.5%	0.04σ	No

Sion's Top win rate ranges from 45.8% at Grandmaster to 51.7% at Bronze across the 10 of 10 ranked tiers with published data for this role — a 5.8-point spread. Measured against each tier's own noise floor, that's 0.27σ at Bronze and 0.56σ at Grandmaster, with only the Grandmaster 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 Sion's power curve as a late-game lean — 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 Sion's kit as carrying hard crowd control — 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 Sion'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.
