The new Prison server has new features, but what drove the old prison map was a PvP economy that many players engaged in. The old map did have it's errors; Massive amounts of bedrock in the building itself which causes a large amount of lag. Then Cypriot added a huge bedrock wall around the whole prison to keep people out of flatlands xD, but really many people already had TP's out into flatlands. I did like the flatlands, it was very unique because the free world was very thin for the massive amount of free players that were ranking up. It gave 2 fronts to raid on or build on. Building farms in flatlands was very easy and I enjoyed doing so. If only you had witnessed the enormous cactus farms people had built. My suggestion is to change the current prison map to more of a PvP based map or to the old map just without the exterior plot area and removing of the bedrock or replacing it. I do also suggest adding a spawner shop or a way to get rare spawners (Iron Golem, Zombie Pigman, Ghast, Witch). Please also look into this plugin: https://www.spigotmc.org/resources/randompackage.38501/ It adds all sorts of stuff, but I have worked with this plugin and players need permissions to access certain parts of the plugin. I do recommend the enchantment system this plugin adds. It would give XP bottles a very valuable role in Prison and also adds a bit of gametime for the free player to work to. You need massive amounts of XP to get even decent enchantments. The grind is long, but so was McMMO if any of you remember :P.
