The benefit of keeping two islands open seems to me that you could have one SMA/RP and one not. However, I fall on the side that all but War Island (which I'm not even counting) and one other should be closed. Everytime a island is closed people are gonna leave the game. At this point, it would probably be better to close all but one to get that out of the way upfront and give people time to adjust, rather than just closing another in another couple of years. I would suggest opening up Dwilight to 2 characters and keeping that as the last island. Open up the west and if in the far future all of Dwilight is even too much space for the playerbase, it is easy to partition off one of side depending on activity, etc, without losing all of the realms/history.
