Did I miss something here? Where does it say in any of the patch notes that WAR was nerfed? Looking through all of them, it's clear that they haven't been touched at all with the exception of the 3.2 patch where all tanks' damage was adjusted to with vitality in mind and enmity changed. That's it. That was the only change that ever happened to WAR throughout the entire expansion. So I'm pretty sure that WAR wasn't nerfed at all recently.
