Alexandrite from FATEs need increase!

[Felis]

Light farming is at least a matter of time and not completely dependant on RNG. With light farming, you're just playing the game and have complete control over the pacing.
With Alexandrite, it's RNG 100% of the way through. Spiritbond? RNG determines what kind of materia you get. Gil making? Play the market--a special brand of RNG all its own, the people kind. And then, there's a potential fail rate when melding it.

Alexandrite 100% RNG? Ha
If you don't like RNG, ignore it.
Do daily expert roulette, buy the maps with soldiery and buy the alexandrite with allied seals. Ignore the FATEs and farming 75 Alexandrite will be time based.
