Love the no CRZ when playing my hunter who can solo everything but the new commanders, farm stuff uninterrupted later at night. I even group to help other out, and it does go a bit faster.
Kind of dislike it on my other toons that are not as good. Finally ran into 2 others and a group of 3 made farming the stuff easy.
To me it feels like the way looting and killing works for this event, is a way Blizz is trying to make grouping and CRZ more appealing?
