I wouldn't want to see a V7 reset either.
I played V5 for while and saw some of the issues that brought about V6. Griefing was one of the big ones, which V6 has largely done away with. Trust me, logging on and finding your build trashed was not fun, and roll-backs were a little weird at times. With the latest update on the Wild commands, granting and removing build perms is easy, and greatly reduces the chances of your build being griefed yet allows for impromptu, temporary build teams. As far as building rail tracks to a friends place, you can do that, as long as it within reach of you free-chunk and money resources. If it were totally free, there would be rail tracks crossing the wild making those chunks unusable to others.
I think Larry has a point about the nostalgia effect. A few of the players that complained loudest after the transition to V6 were also the ones who complained the most during V5.
As for the noobz distribution, that doesn't really impact anybody but the holder of the noobz. The fact that player Xyz has 100,000,000 + noobz doesn't impact a player that joins today from making the same number of noobz, it will just take a while! Which is really what the top money list shows. It is a list of long time players for whom collecting money is an important part of the Game. For me, my noobz represent the commitment and dedication to optimizing sheep ranching to provide a low cost, high volume, dependable supply of wool for noobstown's building needs. (yes, that's a plug for The Shop!
I'm not really sure what removing the noobz held by inactive/banned players would do since those noobz would not be redistributed, and if they were, would only bump everybody up the same amount and have no real impact on the economy. What you might be looking for is a new way to display the stats, plus a new stat or two. The stats (money, mcMMO, etc) are a little stale. Many of the top 10 listed have been inactive, or log on only rarely. Maybe if the lists were to list the active players (10 hours in the last 30 days, for example) with the option to see the whole list. Some new stats might be the amount of noobz used in sign shops, the amount of noobz used in the player to player trade screen, and the amount of noobz traded by /pay [player] 1000. This might give a better idea of the activity in the economy. I don't know if there are logs for this info though.
I enjoyed V5 enough to wait on V6, but I would not want to go through another reset.
