There was a same situation at EU too. When Killian PVP server was kinda of deserted.
Many posts at forums for months, to merge Killian (even with Mystel PVE, as a desperate last action).
The merge finally took place and Killian PVP was merged with Mystel PVE.
When Merging was announced, we had the following disagreement:
**** Mystel players said: We are the vast majority here. The new server must be purely PVE.
Killian players said: At least give us Velika Outskirts for PVPing. Nobody goes there afterall,
Then we had a new mini-riot, because the new server was exclusively PVE and had no OWPVP at all. Not even VO area for PVP. It was like Killian server never existed.
As a solution, players recommended, that channel 1 could be PVP and the rest channels PVE (or vice versa). But this was never implemented.
Situation is complicated, and all actions have to be performed wisely. In the end, some people will be disappointed.
