We've just dropped a brand new Faction Performance chart to help you dive deeper into how each army is performing in tournaments.

Faction Performance chart with z-scores

Why This Chart Matters

This isn't just another win-rate bar chart. We teamed up with Malign Musings to bring you something that better reflects true over- and under-performance in the meta.

Instead of raw win rates alone, we now use z-scores and standard deviations to show statistically significant performance, so you can see which factions are really pulling ahead (or falling behind) the pack.

How it works

Each faction's win rate is compared to the average (mean) across all factions, and then categorized based on how far they deviate:

  • Balanced (Green): Performing within 1 standard deviation of the mean.
  • Outliers (Red): Over or underperforming beyond 1 SD.
  • Extreme Outliers (Dark Red): More than 2 SD from the mean.

You'll also see error bars representing each faction's performance variance, how stable or swingy their results have been.

Exportable Charts!
