So I barely play on the survival server because there is nothing much to do on it, and I was thinking of a server I used to play that had a add-on called Slimefun, what it does is add a whole bunch of recipes and items and new blocks. Plugin link: https://dev.bukkit.org/projects/slimefun
As this is a good suggestion I do not believe this will be added any where in the server. Adding this plugin would most likely cause more bugs then the survival already has and it would also take more time along with taking the "Survival server" even further away from being survival. The Survival server has plenty of stuff to do as it is already also most players quit survival because they don't like the plugins and how far away it is from survival already a new plugin would most likely make more players quit after a few months.
