I noticed this as well right after the shield oath persisting through death change. IL109 PLD, I can keep hate but it seems much harder to do so on a grp of mobs. Constantly losing one and having to provoke it back, where before I didn't have to pay attention. It is frustrating losing mobs, by the time I get that one back, I lose another. Very noticeable in hullbreaker, I had to adjust my rotations quite a bit to make sure I kept hate on the whole grp.
