I think another reason Fractal Continuum is faster than Neverreap is the fact none of the bosses have invincible phases. Neverreap, the 1st bosses dissapears twice until you find and kill his shadow. And the last boss constantly goes invincible throughout the entire fight only leaving you a few seconds in between to DPS him as much as you can before he calls adds again. Yes, the last boss of Fractal Continuum has adds as well, but they are much weaker than the adds on the last boss of Neverreap. You practically breathe on them and they die.
