I won't be deleting EC. It has all the history of this game, in a certain sense, EC
is BattleMaster.
I also don't think it would be fair to wipe out BT - they fought for their island and could've lost it, and won against the odds.
I personally would want to delete Dwilight, but I realize it has the most vocal and aggressive fans. However, here is the player density per island:
According to that, we should axe BT, Dwilight or Colonies. FEI is much better than everyone here makes it, it has the highest player densite in the game.
