Jumping into this discussion 
On Aion there were no dedicated RP servers, so their version of the RPC (Called ARP or Aion Roleplayers) all voted and decided to go to a server called Lumiel. This actually worked out to the NonRPers and RPers advantage, the server was (and still is) one of the most active servers and you never really had a problem finding someone to do something with. The RP community was tight and they had RP events and were generally left alone by the non-RPers (There were trolls though, just not that many)
This is what I hope for FFXIV. On the downside it does make it harder for RPers not in the know to find the right server, but it really a win-win situation all around. NonRpers and RPers coexisting on one server, making friends, and getting things done.
So hopefully they pull an Aion and don't designate servers.
