What changed in the public information, newest first. Data as of . Official means Blizzard said it; Community means a fan site reports it from the beta client; Datamined means found in game files, which can change before release. Many of the numbers on this page are read straight from the game files; some come only from Blizzard's 2 November launch notes because the game files do not have them yet, and those are marked provisional. The How it scores panel says what is still provisional.
Race is a tiebreaker after class, role and what you want to do. For most goals it moves a path by a point or two; for a raid role it can move it more, because there it is measured from the same damage, threat or healing estimate the raid ranking uses. Several racial values below are now confirmed from the beta client; the rest are still from early reporting and could move.
Talents, gear and professions for one class. Treat the talent path as a starting point, not a lock.
A full raid, suggested for you. Keep the players you already have, replace any you don't want, and the open places re-plan around them.
One score out of 100 per race and class, built from your choices. Checked against everything publicly known on the date at the top. Most of the numbers behind it are now read from the beta client itself rather than from demos or press; the cards below say what is still provisional and why.
Blizzard first, then press, then single fan sites as leads only.
