I have the strong feeling, that if you realy wanted to avoid a wipe, even a partial one.. you should have (re)acted accordingly to the bugs/ flawed mechanics you introduced over the time.
E.g. giving away schematics for a tiny fraction of their price..and now you probably even 'compensate' the abuser, making them provit twice. You could have done a rollback to an earlier backup immediately. (i hope there are backups at all..)
Or the mechanic that chars can use infinite territory scanners simultaniously, enabling orgs to scan and claim whole moons in short time. There should be a limit, probably skillable to an higher ammount of scanners..like 6-9..IMO.
But overall the existing world now just leaves the taste of growing imbalance.
I know that the no-wipe-promise is still high valued at NQ, but i honestly dont see how you want to correct the 'system' in a meaningfull fair way..specially for player that come way later, if you aim for a release mid 2022, and all they'll find claimed tiles and billionaires.
On a side note..i don't feel that mining units will do any good to that situation.
