In the past, public land wipes have been adhoc, mostly for rolling in new content.
There were also a time where the "wilderness" was a thing.
Imo, something should be done for the players of MineRealm to enjoy 1.13 content.
While we are at it, also access to end-game-content such as the shulker boxes and elytras.
Also, quartz should be as common as iron.
It's like we, the people of MineRealm, have to run with shackles, compared to the standards of other servers.
At this point, we should not discuss how we want this solved (as opinions are many), but rather reach out for Intelli and let him know we pray for him to implement a solution.
As for updating the server to 1.13, I've heard that many changes have to be made to the server addons (such as the our "staff-tools"). This is mainly due to how blocks now are named such as the bed that now has a different name for each color, thanks Mojang... I bet Intelli wants to updates those tools as a priority.
I've taken the liberty to make a to-do list:
1. Update coreprotect (or whatever the tools are called
2. Update the server to 1.13 (once a 1.13 server version is released)
3. Implement a solution to roll in 1.13 content.
Sorry if I brainstormed too much, but that was my 5 cent. Don't get me wrong, I will always love MineRealm <3
