You build "diamond farms" in other worlds. You fill them with mostly WW's (and FoY's) to get diamonds for your main world(s).Maybe for those in earlier eras but have too many WWs and no room to place and have a Crows Nest too but no room for diamond farms either. I'm in OF.
Players who refresh the wheel and skip the "goodies" may be going for WW's + WW shrink kits for their diamond farms.
