My only worry on this is they would need to give more free transfers for people who are not roleplayers to transfer off the chosen server and onto another. If there was infact another server generated then at least then they are only transferring the roleplayers to that server, the minority out of everyone in D&D Online.
I for one don't want to see any more +1 Loot/XP weekends thrown around because people ask for them or because of maintenance downtime or to gain free dragonshards.. both of these events ruin the economy inside the game and on top of that there are better ways to make us happy.
