To be honest, I doubt there ever will. A higher difficulty mode may make sense to you who may have found the cheesiest way of manipulating the game mechanics into making it easy, but you're of the 0.1% esque playerbase. The majority of players finds even classic mode satisfyingly challenging. Some have even complained it's too difficult.
So if you take into account the amount of work required to make an even higher difficulty mode that isn't only a stat-increase more hp/damage ordeal in order to cater to such a small audience that only exists because they meme the hell out of their sandbox'ey system and then complain about the game being too easy because they're cheesing it out, to me sounds like a bit of backwards thinking if I'm to be very blunt.
They could of course attempt something similar to what I'm attempting in one of the new systems in my mod, which basically tries to detect methods of cheesing and reacting upon it, nullifying the whole cheese thing. Which by nature makes the game harder again. But that goes a bit against their combat design philosophy as you're 'meant' to find those weaknesses, play around and see how well you're able to manage yourself in the world of Rivellon.
Don't be sad that the game is easy. Be happy that you're badass 😎
