Try and walk the same line
The tank will always try and turn the mob with the back to the group. Nobody will pass the line where the tank is standing. Ranged dips needs to stand as a group. So do not spread out but stand close to each other. Try and walk the same line as the tank does. I often see people walking complete different lines and being surprised they pulled a couple of La Tale Ely. The line that the tank is walking should be considered the only safe line. Move as a group. Do not wonder off, stay with the group
