Why didn’t ragnarok devs ever came up with a ragnarok moba?

1- ragnarok was already used countless times by random people to create clones of multiple things, like Pokémon, Naruto, dragon ball, etc 2- ragnarok is an already niche dead game, and using ragnarok to create a clone of something is like creating a niche within another niche 3- guess what? People will always prefer to play the original Pokémon rather than a ragnarok version of Pokémon. The clone usually is either short lived or has a ultra small player base 4- if you are referring to the gravity devs then this question makes even less sense. Mobas and mmorpgs are two completely different things
