How long does the 15th level bard AC song last?? It's not AOE, right? It's only on one person??
I think it's funny that everyone posts their build assuming that this song will be on them all the time during a 15-30 minute raid encounter.... We're going to need to start bringing 3-4 bards on each raid just to keep the 5 melee up to their max AC throughout the entire raid.
