You don't have to put them into just one though. There's nothing stopping them giving some of these hybrid jobs multiple roles but restricting them to choosing one prior to entering any group content. Let RDM choose between DPS or healer for example, they pick one prior to queuing and are restricted to that role once they're in the instance. Problem solved. There are plenty of other MMOs that do exactly this.
