The funny thing is, I recall reading in one of the SE interviews that they intended for Mythic weapons to be MORE accessible to the average player than the Relic weapons.
I remember this too, and what a line of *********** I was excited that I might actually get one of them too, since I had ruled out a Relic because I play casually now and don't have 100 million.
Between the 30k Alex and the 100 other hoops to jump thru, Mythics are only accessible to rich HNMLS members who play 12 hour days, much like Relics. With a Zilart Relic you couild at least pay a Dynamis shell to kill the attestation NMs if you had the gil.
I guess SE expected "casual" players to shout in Whitegate and take a pick-up alliance of people into the Beastman strongholds, into Odin's chamber, and into Salvage (lulz). Then, farm silk threads and beehive chips (because all other drops NPCed for too much and therefore need to be nerfed) for fifteen real-life years to buy Alexandrite.
Having to use rare T4 ZNM triggers, and losing them if you lose the fight, is a deal-breaker in my opinion for this quest. It's a slap in the face, a kick in the nuts, and a rod up the *** all in one. Dear player: Thank you for your money all these years, but **** you anyway. The character isn't really yours, its ours and we can ban you whenever we want. Now, go snap some more pictures and farm that zeni so we can laugh at you again. Kiss our asses, SE.
