Backstory or story content
One of my favorite parts of Mirage Arcane Warfare is those beautiful backdrops and scenery of this magical and mysterious world. I think it would highly benefit the game to capitalize on those beautiful environments with some kind of backstory, maybe even mini single player campaigns or multiplayer campaigns. Say, have a mini campaign with each of the different classes to give some explanation of what’s going on in this mysterious world. Have those mini re-playable campaigns also serve as a tutorial for playing as and mastering that class. Or even just animated shorts like what’s done with TF2.
