A lot of words to detail what basically everyone already knows. It's why Assassin's Cowl (or Stylish on Prismatic) is always stacked with it -- you need the extra survivability to make the playstyle function, and even if you can get it to work, teammates will always get in the way regardless. Not everything needs to work on every difficulty type, though, and trying to make it so is a fool's errand. Some things are just going to work better at lower ends of the difficulty spectrum where "meta builds" are insane overkill.
