Patch 12.1 “Curse of Ula’tek” · Net change

Per-spec net change How much did each spec actually gain or lose? What the notes can prove, and an honest calculator for the rest.

The honest limit. A single net DPS % per spec cannot be derived from the patch notes alone. Net damage is each change weighted by that ability’s share of the spec’s damage - and those weights live in sims/logs, not in the notes. So this page shows (1) the spec-wide multipliers that are exact, and (2) a calculator where the weights are your inputs, never numbers invented here. Nothing on this page is a fabricated net figure.

1. What is exactly known

no assumptions

Only specs with a stated spec-wide multiplier (an “all damage / all healing” line) convert to an exact number. For these, the figure below is the real, assumption-free spec-wide change. For two of them (Frost Mage, Assassination) it is essentially the whole net, because they have almost no other damage change.

ClassSpecRoleExact spec-wide changeTargeted dmg +/-Net intent (from notes)

Targeted dmg +/- counts the spec’s individual damage-ability changes (buffs / nerfs) that are not a spec-wide line - these are real changes, but they need damage weights to net out, which is what the calculator below is for.

2. Weighted net calculator

your weights, transparent math

Pick a spec. Each per-ability damage change is listed with its exact % from the notes. Enter each ability’s share of the spec’s damage (from your own sim or a log) and the net updates live. Weights default to 0, so until you enter them the result is just the exact spec-wide base - no guessing on my part.

Model & caveats (read before trusting a number).

  • First-order: net% = spec-wide base + Σ(ability damage share × its % change). It treats each change as multiplicative on its own ability’s damage, independent of the others.
  • It ignores cooldown-window uptime (a “during Void Metamorphosis” nerf is modelled as a flat change to that ability), and ignores proc-rate, resource and rotation interactions. Reworked and new abilities have no clean % and are excluded.
  • Weights are pre-12.1 by nature (you take them from current sims/logs). After tier sets and tuning, real shares move.
  • For a quick sanity weighting, ability damage shares are on the Raidbots/SimulationCraft report or a Warcraft Logs damage-by-ability table.
