yea, i dunno bout now, but before 1 shot skills were usually avoidable, especially by mages. like i think raptors would tail sweep if you hit them in the back. basically what you had to do was keep the hate facing the tank, and the DDs in front of them, now if someone turned the mob, people would usually die, it also did different dmg the closer you were to the raptor i believe.
It was an interesting mechanic specific to raptors, but a lot of monsters had special mechanics, and ways to take advantage of them.
