I'd like to suggest a regular reset of the end chunks so we can generate new end cities. This will enable players to obtain shulker shells and elytras and also add back in the fun of raiding end cities. When resetting the end it is possible to exclude chunks from the reset if you need to preserve certain builds such as the enderman xp farm. There is also a useful video that explains how to do this which I've linked below.
I know that players numbers are down but for myself who is still a regular player this would be a most welcome change to the server.https://youtu.be/fGlqDBcgmIc
