I heard that once smaller zones have about 40 people in it and 400 for the really big ones a mirror zone is instanced and you have a second one. How does this work?
If i'm looking for a group and and the first zone is full and i want to go to that zone, will then a similar one be instanced? Will i then be alone in the similar one? And when someone leaves in the other one and opens a spot in that one will i then be able to switch instanced zones?
Maybe my perspective of instanced mirror zones is all wrong so please explain.
