Anyone advise running MF in heist?

I've got something like 160ish IR, using IR support + Ventor's + MB with gold flask, trinket and 10 quant from Ventors with 6 quant trinket + whatever cloak I have on my rogue, which I rolled all of them for at least decent IR and 70 to 80% hests still don't drop anything from the mobs. AFAIK, none of it effects chests, so anyone finding better results? Heist kind of currently feels like penny slots.

IIR doesn't have a big effect on mob drops - quant is king, as they say. Anyway, if you want to drop loot from mobs then you're far better off just mapping.
