I just wanted to say that I came across this plugin and thought it looked cool, and randomly generating custom schematic structures on a Survival server instead of those boring villages, strongholds and all of the boring things minecraft have added. With this plugin you can make your own structures and use them for your server, I am suggesting this now because I just came across it and thought it could be game changing.
