The game should have a system where you can hunt other player’s who have high infamy.
Make weapons craftable instead of buyable:
High-grade weapons should only be obtainable through crafting. For example, to make a dragon sword, you need to gather dragon scales and other materials to create it.
Blacksmith- Players that can craft weapons. They cannot become other sub-classes.
Alchemist- Players that can make potions. They cannot become other sub-classes.
Guild Leader- Players that lead guilds. They cannot become other sub-classes.
Quests should be side-based (ex: Making potions for a sick girl, Crafting a sword for a fellow slayer, etc). The “main” quest should be leveling up by slaying beasts, honing your sub-class abilities, and become the stronger you. In otherwords, You determine your future, not the game quests.
Ranked PVP: Like Celtic Heroes, but every time you enter the arena, you pay a fee and you fight a random player.
