You would think so, but I feel it’s caused more harm than just having a “normal” difficulty for normal people and not care if the top ones clear it fast.
I’m talking about like… most bosses being around Normal, a handful of later ones being like early Heroic bosses and maybe the last boss (second to last boss at most) being the level of an early Mythic boss. If the top people clear it super fast it shouldn’t matter since they are a small portion of the players.
