Based on the original post, this is how I would describe what is listed.
  • DPS checks aka performing perfect rotations (Difficulty)
  • RNG (Need to be more specific, random boss rotations are difficulty)
  • Twitch Mechanics (It depends)
  • Scripted mechanics aka memorization (Difficulty, but not preferred)
  • Team jump rope aka finding 8 people who know the fight (Neither, this is just proper preparation)
  • Content gates or lockouts (Neither, just a restriction)

Things I am against, overuse (not all) of one shot mechanics. RNG that makes something impossible based on uncontrolled circumstances, haven't seen too much of this in this game thankfully. Memorization can be tedious, I prefer mechanics that are based more so on adaptability.
