>>430845XIV fights are all scripted with little to no variation. The same mechanics and phases happen in the same exact order. Or if they do change, they follow specific patterns that allow you to predict the next 1-2 minutes of the fight.
You literally pull, die to something, learn what killed you, pull again, do the mechanic, die to the next thing, repeat.
The biggest walls in fights lie in that failure to play jump rope immediately results in your death, which if it happens at the wrong time, results in everyone dying.
