Community Day Heads/Skins Question

Has anyone ever actually gotten these to drop as loot on PC? I’ve seen people get them on console but never on PC. Is there any possible way of getting them aside from farming for 100s of hours, or are drop rates higher in DLCs?

I’ve gotten the head for Zer0 from Rogue once, but that was back before GBX fixed it so we could pick them up. I haven’t seen any of the others, though, so they’re a pretty rare drop.
