There is indeed no gear drop in FF14 but only mats.
That's mean you "farm" mob to have mats and craft the gear.
No "special" gear from drop nor in dungeons. The only "special" thing you have in dungeons is skin but no effect or real stat boost.
(btw I understand you. I liked farming mob for a rare special piece of gear that feel really better than common one but unfortunatly that doesn't exist here, only the ilvl matter)
