I have had the same epic gear showing as possible prizes from pachinko for a while now. It doesn't seam to change with time or as I level up anymore. All of the gear is for the lower right equipment slot, 2 swords, a radio, a scepter, a present and a treasure chest. There was also a briefcase in this group but I won that a while back. The briefcase I won at level 119 and I am level 136 now.
Why is the prize gear not changing anymore? I have very little incentive to pull for pachinko since all of the epic gear is for the same slot.
