My server relied on terrain because an enormous map cannot be constructed of bricks when it reaches the brick limit and lags.
Terrains allowed a large landscape of easy to load land.
I haven't played Blockland like I use to since they were taken off.
I would continue playing if they added something else besides having to build it all or a much larger brick limit with less lag. Other than terrain, I can't find a way to have large maps that don't cause lag, or reach the brick limit.
