It's not really viable at this point Snake, there would be no point landing at any of the Trials of JiangXi point for anyone BUT SCRA so it's kinda exclusive and not conductive to expanded role-play.
Right now it's best for either a Docking Ring like Tangier/Crete/Mata etc etc or simply a satellite like Nuremburg or Leeds because it would allows others to be included in the RP process and is less messy to deal with/less work for Devs.
As for Volgograd (which is our Capital World and actually holds a fair deal more than JiangXi in terms of Population) right now it doesn't really NEED a Ring/Satellite as most of this RP focus is on JiangXi and it's recovery from it's bombed state. The reason I suggested JiangXi was due to the ongoing RP process of the world's recovery and the opportunity this would provide to those seeking to trade more with the Coalition such as the Hessians/Freelancers/LWB etc etc, it's frankly has more 'RP Potential' at this time than Volgograd does simply due to the past history JiangXi has.
