A new player builds with rocks or wood and will not reach 300k prestige. A new player is going to farm the blocks with a copper tool, which will take forever. Just the rock requirement of a single brick masscraft will look insane to him. 300k is A LOT!
If you’re able to get to 300k prestige you’re using valuable materials like iron blocks, bricks, a lot of gleam, deco blocks, or something like that. You will have forged 3x3 tools. And if you have forged 3x3 tools you will get a lot of XP and therefore plots. if you’re 3x3x3 village needs protection, I’m sure you can spare the plots. You won’t depend on the free 2 plot wide reservation.
