To quote your own description of your game
"Hardcore and realistic, Life is Feudal: MMO showcases medieval life on a grand scale. Players will use survival skills, immersive RPG features, a thriving economy, community building, diplomacy and warfare to survive and flourish in the unforgiving world of Abella."
It is key to note the wording of this description, for the words chosen represent my point "Unforgiving World of Abella" not worlds, World. There is no plural.
Until the developers recognise that things like this as well as lack of meaningful content updates are a real problem, there will be little positive outlook for the future of this game.
There are many other things that we can point out, overpriced Skins, updates that make it appear as if the developers have zero clue about the game their players are asking for and believe they bought into, such as the recent changes to horse stamina making it a giant pain in the ass to travel across a map that is designed in such a way that travelling long distances for any kind of content is going to be part of your experience. When things like economy are non existent and instanced battles are barely functional (one of the only content features player can currently enjoy) are seemingly made to appear less important by such ridiculous changes it's no wonder the player base have lost faith in the game.
I could continue on endlessly about the issues that are present, but alas I do not wish to write a book that i don't believe is worth the time to create, so i'll end with this.
Life is Feudal is a niche game and you cannot please everyone, so please focus on the audience you wish to attract and build upon that. To quote a friend.
Make Life is Feudal a open world survival medieval simulator AS PROMISSED - Period. If not, I'm out!
