I've done A1 and A3 with 3 bards (1 of them being myself). Bards are pretty much fine now. I wish they wouldn't have nerfed Sidewinder, but oh well, the extra DoT damage from WM makes up for that and more.

I think they are close to where Bard needs to be, they could probably tweak it slightly to boost its DPS just a bit, but people who are complaining about having 2+ bards in a group and not being able to clear it are just clueless.
