Okay read the entire thread and you will probably understand the point.
First of all, I believe that another server should be created that is just PvP only with 25% suppression fields for all the 75% fields and a lot of the 25% fields should be turned to 0%.
Allow character transfers or account transfers to that new server and then once people move to the new server (which would be a great deal) you can then merge RK1 and RK2 together.
Balancing characters would be easy. On the new RK1 server you could remove PvP or minimalize the fields considerably as it would be mostly a PvM server which would consist of friendly teaming, group organization, and working together. For storyline intros and special events you could make any zone 25% for the duration of the storyline event.
On the PvP server, you would do a few things differently. First, either implement faction for killing sided guards and/or make them invulnerable to AE based attacks by sided personnel. This way you allow those that use AE tactics to not become attacked and hurt by sided guards. You also add more depth to the story by having conflict which inturn boosts role play.
On the old RK1 you can still have PvP mind you, but I would make it a lot less and this would cater to the people that do not enjoy PvP but instead enjoy the hunt and the ability to group with friends.
So to reiterate you would have 3 servers.
RK1 - non-PvP or very diminished PvP.
RKP - PvP server with 25% / 0% zones - no 75% except for in-city shops.
Rk3 - German Server.
You can add your insights to this.
