The secondary stat priority for Arcane Mage in The War Within, aggregated from real Mythic raid and Mythic+ logs on WarcraftLogs. Higher percentage = the stat top players itemize more of. Use it to pick gear, gems, and enchants.
These weights reflect how the current top Arcane Mage players actually gear, not a fixed stat weight. They shift slightly between raid and Mythic+ — in M+ you'll often value a bit more survivability/versatility. Always hit your required ratings and your spec's breakpoints first; treat this as the tiebreaker when choosing between similar item levels.
