Not really seeing it as much with WARs, but I've been seeing a LOT of PLDs having hate/enmity problems while playing the new content... tanks are constantly getting mobs pulled off of them, and I was wonder if perhaps the change in 2.3 to keep Shield Oath constantly applied might have messed up its enmity?
I've seen people spam flash and still have a mob or two trail away momentarily, and in general I never saw this level of hate-loss prior to 2.3.
