It's not in the 3.0.8 patch notes, but apparently Paladins should expect removal of all threat from Judgement of Light in the next patch. This is being done to address the wonky nature of JoL threat -- since for fights in which large portions of the raid are taking damage it gives a huge threat boost via healing threat, while for fights in which only a few raid members are taking damage it only gives a small threat boost via healing threat. Or to put it concisely, as forum poster Tippocabra did, "threat from Judgement of Light is not consistent." The new "no threat" JoL should be nothing if not consistent, though it has some tanking Paladins concerned about reduced threat. (For Retribution or Holy Paladins who have ever found themselves using JoL in a group situation, however, the threat decrease can only be a good thing.) Ghostcrawler assures us, however, that this is not meant to nerf Protection Paladin threat -- and though he doesn't go into specifics, we have to assume that means the threat Protadins would previously receive from JoL will be coming from elsewhere.
