So far so good, HSR apparently made their endgame MoC harder after a while. I wonder if they'll do the same with Shiyu and add a floor or two. I think Deadly Assault is pretty good, but more bosses with different weaknesses and resistances would help a lot to shake things up for difficulty. (Imagine two fire weak bosses, would get you to use S11, Evelyn or Burnice, or even get creative and use a non fire team) I feel like most players would just default to X team for Y boss over and over again.
