I dont see SE going away from QTEs anytime soon. Yeah the punishment from the last trial is hard if someone fails it. No doubts about that.
But QTEs are a measure to determine the struggle of our character and personally i found it very fitting here because (spoilers below)
We've been teleported to the abyss and our total defeat was imminent. Ofcourse our character struggled to stay alive and to avert the inevitable.
It was the final trial of the shadowbringers story so its alright with the difficulty. For me at least.
