Increase map size limit

[The Arena Master]

I would love this.
I've been raided twice, both times my base has been super far underground within 4000 blocks plus of the spawn.

The anarchy server I play on , has a MASSIVE map. I chose to go 20k blocks from spawn before building and I still hadn't reached the border. I feel the survival map is so crammed , and that theres nowhere to go after being raided.
