I personally have no problem with minerealm as is, but I am a simple man with simple needs

. The following is for inspiration mostly for better ideas and since most players and new players seem to want an updated map and more obtainable resources. I have no idea what I am talking about, here is my idea! xD
This idea has two basic principles regarding a public wipe, based on the complaints and concerns showcased on this thread.
Step 1: This method would sell back any private realm to the server which does not have at least TWO realms adjacent to it AND is NOT part of a cluster of private realms 2x2 realms large or more at FULL price (this includes diagonal realms and strings of private realms) So any private realm which does not have private realms on two of four of it's borders, and is not part of a cluster of private realms at least 2x2 realms in size, will be sold back to the server at FULL price (no tax) and made public. This will accomplish three things, 1. instead of random cliff edges and sudden drops all over the map etc, there will be more fluidity to the terrain with a public wipe, 2. large clusters of private realms and all it's builds etc will be untouched and 3. Those who lost realms can buy the same number of realms back and choose where they want to relocate based on the terrain change
Step 2: The second part of this method is that all realms bordering the private realms will NOT be wiped, including diagonal realms. This gives the private realms room to breathe so after a wipe, 1. realms aren't flooded or encased by cliffs 2. Public realms bordering major clusters of private realms tend to be where private realm owners branch off and players without realms start off. So less loss of items and builds 3. This will also help with the terrain irregularity issue after the wipe.
The basic idea is to carve the map into sections, preserving large concentrations of private realms and it's immediate surrounding public land and wiping miscellaneous private realms in the middle of nowhere, while giving those realm owners the opportunity to purchase the number of realms they lost back according to the effects of the wipe. All this while keeping the integrity, aesthetics, and history of the map in tact, updating the majority of the map in large sections for new players and vets alike, and most importantly, keeping MOST people happy

Those who will lose realms will be given an opportunity if they so choose to clear out, maybe purchase a realm near other realms. I'm sure there will be time before this happens to go out and protect builds by purchasing occupying public realms in bulk, but this will solely be an effort of the users (if it really matters to the community, people can find these builds in public land, post about it on the forum, and raise credits to purchase them. Benefits of donating including realm perms, just an idea:D) And regarding private realm wipes, I think if that is implemented should be made possible only through staff request and a one time thing.
Well there you have it, again I have no idea what I am talking about, I don't know if this is even feasible, I am just a dreamer (but I'm not the only one)

xD Tell me what you think (be gentle) ._.
