The change was during the times Zone had very little players and it was to try to influence more players to base with a more free-for-all basing, that is similar to Era and Classic. It was also due to the small player count that usually one squad owns all the planets, which we had to change for smaller squads.
However with the release of squad planets and an increase of players, I also would like Iricia, Choros and Conquest to change back to how they originally were, but have Iricia as classical Zone PC Style and Choros as how Ghetto suggested, to create variety.
