The biggest issue with being a Bard is that when something goes wrong and the group wipes, you're left mentally going through your scores of songs and abilities, attempting to configure a combination you could have McGyvered up in a split second that would have saved the day. If I had 100pp for every time I took one for the team mezzing highly resistant mobs that inevitably reduced me to paste, giving everyone else time to zone, I'd have a BoH by now...
P.S. I'm a pretty ordinary puller personally, but here's an interesting legacy post from Thott that gives some insight:
