Arah was hard back then and even to this day, I couldn't find a group to play it. Luckily there was PvP that lets me get all the weapons and armor. If Arah had an easier mode, I could learn how to play Arah. Fractals had difficulty tiers and it let me learned the Fractal. If T4 was the only mode, I would probably could never get into fractals because no one would let me join. They would demand that I have 10,000 Pristine Fractal relic before I could join a normal run.
