Tuning (Source)

With Judgment’s cast frequency increasing in patch 10.0.7, Judgments of the Pure has been overperforming as a PvP talent. In a hotfix being applied this upcoming Tuesday, the talent will only apply to the Paladin and no longer have its effect applicable to allies.

Judgments of the Pure (PvP Talent) now causes Judgment casts on an enemy to cleanse 1 Poison, Disease, and Magic effect they have caused on you (was allies within your aura).
