well. it would take some work but it can be done. to just having 1 single server. (with extra instances as it were to make the layered server) possible. that way the map Uruga isn't full all the time because map Uruga becomes instance 1-3 and you can jump via the teleportation gate... that would support it. and the community would be able to grow with it. (i'm sure we'll come up with an idea of saying Instance 3 Uruga is often vendor city.) but that is up to game company's decision. either way it keeps us all together. moving forward and putting us in line with events et el.
I remember gamigo outlining that after they completed the first merge the amount of active players went down.
Now I will agree there weren’t any meaningful patches etc after the merge was done and this probably paid a huge impact on that.
However, if those are the statistics they are running on I doubt they will bother doing another merge.
We can hope though.
