They shouldn't, unless they let everyone know that their WAR only use a shield and let the leader make the decision.
It's downright disrespectful to join a PUG without letting the leader know about shield WAR and role playing though.
It's pretty self centered to think "I wanna play as a shield WAR cuz I love role playing, so everyone else should tolerate my WAR even if I'm slowing down the entire pt"
