did yesterday too, kinda disappointed by the reward of the special assignement and the fact we can only do one per week. the item given are kinda garbage for a lot of us... maybe with the expansion they will get usefull... but since it's faster to level up in the palace of the dead, what is the point of scroll increasing the exp earn, seal, symbiose and such.
however some new affinity are kinda neat like have a % to get materia as reward from a mission.
