Claimblocks remain an issue on Vanilla. The limited number of claimblocks stifles what can be done in the world leading to experienced players quitting and the server dying. Were experiences players staying to play on the server as they could actually continue to work on projects leading to more players being on the server encouraging new players to stay. While there have in the past been suggestions to fix this issue, it seems they have been either unheard, or ignored. So I’m going to suggest that similar to how on survival you can buy claimblocks with your balance, you would be able to buy claimblocks on vanilla with the diamonds in your hand. I would suggest so that 1 each diamond can buy 2 claimblocks, and while that may sound like a better deal at face value it's actually worse when you factor in MCMMO and the use of superbreaker.
