Nah, for my money dark roasts are best black, either hot or cold brewed. If brewed right, they’re super smooth and flavorful, no need for anything else. People usually don’t have enough coffee to water and that totally ruins dark roasts. Higher acidity of light roasts lend themselves to balance with cream and sugar. And those opinions seem to be common among the thousands of people I’ve personally served coffee to. Maybe try listening to people about what they say they like, instead of jumping to correcting them based on your tastes.
