As said above. It rlly gets out of hand. There are always mesmers that pull you from one side of the wall down on the other side. 600 range is just too much.
We'll you could say necro pull is 1200 range. But you need LoS.
You cannot pull someone from one edge of a wall over the whole wall down on the other side.
Mesmer can. Because no LoS required.
That makes defending objectives pretty hard since people can be pulled out of their defending siege weapons pretty easily.
