I have tried to get a straight answer out of Support but they claim there is nothing wrong with the passes, but is it normal for the Superior Green CoF passes to give you a dungeon run with level 73 mobs? That is what a Purple run should give you. Regular Green passes give you mobs around level 130.
Superior passes for dungeons are just slightly tougher than regular purple pass dungeons. Each dungeon does it a little differently, and some of them may contain more mobs at slightly higher levels and have different chest drops. Due to the dungeon revamp update, regular green and red pass dungeon runs now have much higher level mobs and have their new respective item drop list, such as death beads from CoF, hell beads from VoH, crystal materials from GCM, etc. Whereas regular purple and superior purple, green, red, and black passes do not.
