I think roles are a great discipline for the designers in a game like 4e. In 5e though it could be harder to see the use. One thing would be to have role as something that can be added to class lile a theme.
Thus there would be fewer classes and boradly defined. Like the fighting man, magic user and holy man, with roles giving focus to the base concept.
