1. Don't put new player's towns under occupation for being peaceful. They get confused and quit. Do it after a week or more.
2. Add a forced interactive tutorial. I asked who read the starter guide to my new residents, only 10 or 15% said yes. Basically it's a wall of text that nobody reads. Then they ask, how do i earn money, how do I build a ship.
3. Add a way for new player towns to grind xp without going unpeaceful. Let peaceful towns use spawners or let them obtain all enchantments.
4. New player pvp protection gets removed when you attack a MOB. Fix this.
5. Confirmation for /suicide like for /pay. That stops people from tricking new players.
6. Force the texture pack for new players, i saw people say the server's shit because they thought guns were renamed silent crossbows. You got to understand, the average player is too lazy to manually install a resource pack for a new server.
