I believe this is making a storm in a waterglass as we say in Sweden. - SWTOR has plenty of people having bought the game and plenty of those are bound to be roleplayers and I am sure that we in the end will need more than two EU-RP-PVE servers.
I wish both servers well and am also 100% sure that both will have great communities. As far as I understood it prior to all these talks (enlighten me if I have misunderstood anything), was that the alphabethical order - the first one - would be the superserver and it seems as valid a method as anyone else to use.
I don't believe anyone should change server, they should more likely choose a server they believe in and then try it out for a while. Myself and our guild, CIB, will be at the Progenitor for two reasons: A - We were deployed there and will of course try our surroundings out. I see no reason for why we should change before we even know if the roleplaying community there will be a success or not. B - As far as I understand it, that server was also the first in alphabethical order which was announced earlier?
Anyways, please don't get a heart attache anyone. There are LOADS of roleplayers coming in and BOTH servers will have a great RP-community formed. I am sure of it.
