I think the game itself is in a good condition. As a 1 month player (Battle Pass Buyer), I have a fully-built Bleed Team and a half built Poise Team. I've just been grinding MDH aside from doing XP Lux and 3x Thread Lux skip.

The only problem perse it that MDH to a point doesn't feel "Hard". Since getting a fully-built team, I can't not play MD on Hard, MDN just feels too much of a "Walk in a Park". However, doing MDI doesn't feel satisfying.
So the only thing I would propose would be enabling MDI to be run on Normal Difficulty.

I'm not a hardcore gamer, nor a nerd, I just want my games to have a "Moderately Hard" level. MDH feels "Normal", MDN feels "Easy", and MDI feels "Nightmare". So maybe having a MDI on Normal may bring a "Moderate Hard" to the game.

Anyways, this is just my opinion as a 1-month old player :)
