A single-page documentation site summarising the class changes in the first World of Warcraft: Midnight Patch 12.1 "Curse of Ula'tek" PTR build ("DPS cooldowns nerfed").
Live: https://patchnotes-overview.pages.dev
- Transcribes every class/spec change from Blizzard's official developer notes.
- Computes the exact percentage change for every numeric line in code, from the stated old -> new values, so the math cannot drift from the source.
- Adds a cooldown-squish scorecard, a biggest buffs / biggest nerfs breakdown, and a grounded reroll guide.
Percentages are not typed by hand. For any change that states an old and new value, the page computes:
change = (new - old) / old * 100
So a shield that goes from 40% to 50% of damage is reported as +25% (not "+10 points"). Where the notes only give a relative figure ("increased by 20%"), that figure is used as-is. Direction (buff / nerf / neutral) is judged per line by gameplay impact, so a shorter cooldown or cheaper spell counts as a buff even though its number goes down.
We deliberately do not invent whole-spec net-DPS numbers, because real throughput depends on uptime, scaling and final tuning the notes do not provide. The "biggest buffs/nerfs" and reroll sections are an interpretation of the direction and size of the stated changes, not simulation output. This is a first PTR build; values will change.
