That island will have no influence on the game at all. Too small players there. I don't see why it needs to be fixed, and I don't see why people even care about the "problem".
Or you do not see the problem of US servers. US servers needs stronger players around the core and the rim. Most of the worlds here have a strong core. To beat players here you need to have strong players close to the core. And in my opinion there are not enough good players in between the rim and the core.
If there are isles at a TW world it is a loss of people who have their first village there. Is makes no sense to build a imperium there.
