I seen that Even if the relic is better then mystic it still only makes the player enter dyna 3 times, everything else and be bought out of bazzars or off the AH. That though was the best case many LS leader used other to farm the currancy with the possibility they could be next in line for one. Not say thier wasn't shell that didn't hold true they were few and far between. Then there were those that did buy gil to fund in part or whole the cost.

I'm not dismissing the usefulness of most relic over mystics but mystic offer more challenge then just having the gil to finish it.
