These dungeons are all about staying motivated and putting in the time. My linkshell does nothing but AV and Cutters since figuring out Garuda, determined to have all of our jobs outfitted with Darklight before 2.0 and/or as soon as possible.

It gets depressing sometimes. We've had our droughts. We did 100+ consecutive speed runs on a stretch 2 weeks ago and didn't see a single piece of Darklight drop. No hands, no heads, not even DL boots.
We stuck with it. We got through it. We stayed motivated. We've since gone on a Darklight tear and been extremely fortunate in our drops, averaging 3 a night.

The drop rates are fine. Sometimes frustrating, yes. Sometimes you feel like the FF Gods are punishing you, yes.
But then it breaks for you and your linkshell and you feel great about not only your new drop but the motivation and commitment put forth by everyone amid a sea of QQ `i give up, this isn't fair` QQ.

Now i'm two drops away from completing two full sets. Been a long and sometimes bitter road with many nights only bringing about the disappointment of nothing but Mage Pattens and Scorpion Shields. Now it's getting closer to being behind us.
Stop QQ'ing, keep your frustrations to within your own linkshell, and just keep at it.
The bad luck will break for those that remain motivated.

Darklight is rare and should remain so.
Asking SE is nerf the drop rates so that all of Eorzea has it in a week (these dungeons are not difficult...) is in fact only asking for SE to deprive you of the victory and fruits of the hard work you're all here claiming to have put in.
Chin up, food up, and keep at it.
