litematica is the real problem. Half of schematics are straight up copies, the other half were designed in creative flat worlds and don't fit in with the environment they're actually gonna be built in.
That's fine for underground PvP bunkers since nobody sees them anyway. But for surface towns, the best ones are built naturally by many people over a long time, like real cities. Think Valinor or Arvik. They weren't spawned in by one or two people (TICAN)
Easy place accelerates schematics, schematics are bad
