I know this might be a silly thought, but say I wanted to meet up with another character on earth station, how exactly does one do it when there are dozens of instances of the same place?
This is where the whole one big server concept breaks down if we're not actually in one big server. I'd rather see a thousand different game servers than deal with "I'm on earth station #65, what earth station are you on?" It certainly does nothing for the immersion factor.
Yes there's the "bridge", but is creating a private group instance really the only option to meet up with friends?
