If we want any chance of keeping at least 50% of our playerbase, we should not wipe all the worlds.
The effect of wiping the worlds would be incredibly damaging. The cons outweigh the pros here. I've heard mention of Prism and other grief trackers being tested, so maybe make copies of the current worlds and test those plugins.
fssp Selections can be pasted while discounting air blocks (-a) which is known to significantly improve the performance of block operations.
This is not a solution to the issues there are, which is that many OPs have their builds integrated into the terrains, such as in Fazbender Entertainment in the overworld. That is why Pyro is saying it's not possible to paste schematics. If you look at the Imperium as well, it's the same thing - many of the builds are designed for the specific areas of those terrains such as islands in the End and it cannot work unless the islands are copied too (which totals to an approximate 1 billion blocks).
Wiping coreprotect would also not be beneficial to the OPs either, as yet again some OPs have big-scale projects like the Imperium which have been worked on ever since the deletion of TF.
With all of the reasoning above, I object.
