How do you farm in this game?
Erm, I dunno what you mean about mob drops honestly. If you mean drops from specific DEs then I’m not really sure, but regular farming of mobs for specific crafting mats and stuff works fine forever. I have farmed spiders or such before for 1+hours and still gotten the same amount of drops, including rares here and there. Maybe you are just getting unlucky, but I’ve never had an issue where I just stop getting loot all together.

Try it yourself. Start grenth event (the one where they descend from dropship on the shore). Use some AOE ability to tag every mob in every pack. At first, you’ll gather lots of loot. Like every monster out of pack has a drop, and most have items in them. And then suddenly, one out of ten has a drop, and its mostly nothing, or a single fine craft item.
