The first time the bard early pulled with Foes Requiem, I said "Hey watch the FOEs." and went with it (he locked out four people). Then it happened again on the last boss and he tried to push it on a summoner...

I'm not one to antagonize people, but please get into the habit of playing swift song after an encounter bards, because that way you will never unintentionally pull additional monsters or lock people out of a boss. This was in Syrcus Tower for anyone wondering.
