First boss of the 7.1 dungeon left me with massive eye strain and an instant headache because there were so many flashy effects going on. If my friend hadn't been playing the Warrior tank of the party, that run would have not been completed, I think. Luckily, we were able to finish after several wipes. It was really awful, and now I'm kinda afraid to run anything else in the patch knowing that enemy effects are just this bad and there's nothing I can do about them.
