You can't customize your character. You're stuck with that character appearance when choosing a class. You can't even change the gender.
There are no NPC shops. You can't buy or sell items.
There isn't enough NPC or interactions to do, especially with other players.
There's no auto fight, which is good for me! However there was one instance when I couldn't hit the monster. It must've been a bug.
It has potential if they continue to add more content. But the way it is now, it's hard to immerse and feel like you're in a 'roleplay' game.
