Well, the 3% free hit from precision has been removed from all that were effected by it. Zharhym posted about it in the forums (source).

During the transition from patch 2.4.3 to 3.0.3 the following talents were not unlearned properly by some players, resulting in those players still gaining the benefits despite the talents no longer existing in the talent trees. As a result, we’ve pushed a hotfix which has corrected this matter and affected players will longer receive credit for having these talents.

Warlock: Improved Lash of Pain
Warlock: Fel Stamina
Shaman: Totemic Mastery
Shaman: Improved Lightning Shield (Rank 3)
Paladin: Precision
Rogue: Fist Weapon Specialization
Priest: Shadow Focus (Ranks 4 and 5)

If you were lucky enough to have the ghost hit, it’s time to re-gem your gear I think!
