Don't forget this game don't have a proper ranged physical damage dealer and people pick archer because of the logical assumption that if it wear light armor and wield a bow than it might be the class that they often play in every game. Up to lvl 30 you play as pure dps and once they change into BRD most players might go "oh.. am I a support class!??" or just keep playing the way they have been. Nonetheless, I'm yet to find a bard who refuses to use his songs once asked. Maybe if people would consider the other side they would feel less frustrated. Communication might be the keyword in this case.
