1. The ability to marry. This will allow players to use the gameplay for better role-playing. It would also be possible to add this feature to two players on Lotr servers.
2. The ability for players to create faction outposts for a more flexible conquest system. And the ability to occupy enemy forts.
3. The ability to find a crafting recipe scroll that is not available for the selected equipment or item faction. For the balance of each item or item type, you can arrange a separate receipt each.
4. The ability to initially select the player's race (but not the faction!). Each race can have its own advantages and disadvantages. Choosing a race will not only allow you to immerse yourself in the game, but also allow each player to fully play for their favorite faction. And someone may want to play for the dark faction, while playing a representative of the forces of light.
5. Add the cities of the factions marked with dots on the map. This is possible with random generation for the first time. This will not only give the world scale, but also make it more alive. But it will also give you flexibility for battles, especially on game servers.
