Some of this stuff will be implemented over time as the game grows and progresses. New things will be added all the time.

- please implement new countries because the world is too small !!!!
New areas will be added as the game grows.

- much more vanity gear
More will be added as the game grows.

- flying
This has been brought up before and tbh I do not really see this happening in the open world as flying would conflict with how the world is built from a technical standpoint. Maybe in certain instances and dungeons though.

- swimming and diving
Again, don't see this happening as the world is not built for it.

- more rare mats
As the game progresses.

- more titles
As the game progresses.

- food should be important for the character to survive.
Food can be important for survival in the hardest content But joking aside, I don't see that happening either as this is an MMORPG and not really a survival simulator, just not that type of game.
