Current game version 468 talents synced with the live game client, including all launch-week tuning (hunter shots, feral raises, the paladin tree rework, warrior threat) and the Nov 4 warrior hotfix. Effects remain English originals; not independently verified in game.
Upstream keeps moving (encounter designer, healing sim in flight); hunter's Improved Serpent Sting comes from the client-cache side after wowsims retired it — see the Nov 2 dev notes , the hunter shot report and paladin changes . Plan against in-game reality.
