I would like to see the addition of MORE ISLANDS far further up the priority list !
It will open up the world and give smaller groups a chance to establish new alliances in new territories.
I'd also really like to see 1 or 2 of the new islands being "no build/no base" areas, i.e. you can only teleport in and exploit resources (NPC's, minerals or other players). Everything you gain there has to be transported off the island.
Make 1 island only accessible from beta territories, and the other only accessible from alpha, but make the resources/NPC's equal to beta islands, and both have the same pvp rules as beta.
