I personally think there are many good things about iZone. New elements and different things to do there.
However I just think it's essentially the same as iEra. I personally believe that if iZone came out BEFORE iEra, then iEra would be having this problem now rather than iZone. iZone has a lot more different things to keep one busy imo and probably because iEra has such a large and stable community, a lot of players don't want to start over and make the transition towards iZone.
The development-related staff all are pretty nice folk and really do try to work towards making something out of iZone. On the other hand, I can personally say that the GP-related departments really need to work on their policy/work ethics. I believe the GP Administrator (or Chief) is still immature for the job (probably first time being head of a dept.) or needs to realize that his position isn't one of superiority and punishment but rather one of good service to the players.
