This is jst my opinion.
After doing around 10 fates, I realise its just a waste of time so I dont even bother to farm for them. firstly, doing low level fates repeatedly is not even rewarding. For those replies that say u can earn gils and seals along the way which u can spend on vendors, thats jst bullshit because the amt earned is so little its redundant. I say its a flawed game mechanic, maybe if SE lets us hunt them without equipping our zenith weapon and able to farm them cross-classes as long as the quest is undertaken, that would make sense. Either that, or increase the drop rate of atmas which is the point of this thread. if not, this part of the quest will remain a barrier for casual players to continue the zodiac quest line.
For those that say that yea its suppose to be designed like that so it'll be a grindfest where it is suppose to not be easily attainable, i think u muz have had too much time or pretty hardcore.
