Early access wipes of land-based structures make sense and are completely reasonable...land geo changing, islands rearranged, WPE need unclaimed space, etc. I'm not convinced that a wipe does anything for player balance.
In the event of any next wipe, can we keep our characters? Maybe even a ship (with whatever we can carry on it) if it's anchored in a safe space and we're sleeping on it?
I think this would help keep the player base active before major game-changing events, increasing regularity by reducing wipe anxiety.
