Really quick note on a Patch 5.4 hotfix posted this evening:
Evil is a Point of View should no longer incorrectly cause Turn Evil to affect targets that are immune to loss of control effects.
This refers to the new level-30 paladin talent that allows pallies to join the ranks of classes with an option to use a fear against enemy players. Since Patch 5.4 went live yesterday, pallies with that talent were able to use Turn Evil to fear rogues (among others) at any time — including while they were in the middle of a Killing Spree, an ability that should be impossible to stop.
And now, assuming the hotfix works, it will be impossible again.
