A good way to fix the community problems imo with the upcoming server merge is Simple. All SE has to do is simply leave the ability to x-fer servers in well after the merge that will allow the players who for whatever reason were not able to switch to the server they wanted to due to maybe not being on the game for unforeseen reasons.
Also this will allow those whom have been inactive but were planning on returning to link up with the players that they were playing with in the first place.
Another possible solution is if your doing this in order to better populate a server due to low population simply merge two low population servers in together without making people actually have to apply for that server. Simply combine two servers into one server , it really cannot be that difficult at least not as difficult as going through a much harder process as in making everyone choose a server and if that server is full having to choose another one which will frustrate alot of people if they are trying to go to the same server as their linkshell and or friends.
By combining two into one it eliminates so many of those problems that will occur some of which might even cause people to simply stop playing altogether which if im not mistaken could cause a domino effect later on and wind p causing more people to leave than was initially expected.
