The solution is not another unofficial RP server that will collapse or devolve into little more than 10-50 person clique spread out over 2-3 FCs.

There are two solutions to this issue:

(1) RP is consolidated on one hub - Balmung; OR

(2) RP is consolidated on one hub - Official RP server.

It doesn't matter which alternative happens; what matters is that RP is consolidated on one server. SE should take the exceedingly simple, cheap, and effective step of designating a new RP server and make transferring to that server for RPers seamless. This benefits everyone. RPers are able to have the community they need and value. PVEers can avoid RPers if they desire.

The OP's proposal is what needs to happen.
