We didn't take the druids away!
Firstly druids don't have to worship a god to cast spells. While it's generally a conceit of Forgotten Realms, it has wormed its way into other settings. Scarred Lands druids have no such problem. This also means they can have metal weapons since some (if for say they pay homage to Thulkas, the Iron Lord) can use that since it's a believeable way for them to "honor" their patron. And even with "Denev" in charge of the world, some can (at the expense of a wild shape) find a way to channel the power of their patron to make them more like the "cult" leaders they once were.
Even those that don't believe in titans can follow spirits instead. Admittedly I'd prefer for a shaman class to do that, but druids will fit that bill for now.
That explain that one to you Drowsbane?
