Math, Materia, and How to Succeed at Melding

[tymora]

Actually moon-phases and directions had an effect in FFXI, so why not in FFXIV? If not this, the moon-phases didnt need to be there at all.

Actually it never did in FFXI. Took down synth data for over a thousand synths back then.
People just like to believe in whatever they want.
(And because the programming team is different.)

I double-melded Colosseum Loincloth x 2 out of 5 before new moon started.

End of the day, it's a "religion". Just believe in whatever makes you feel good. No need for proof. Even if there is proof to the contrary, people will still think moon phases have an effect.
