^ What Itchybottom said.
I posted a theory
here as to why Bards work here but didn't on live.
I guess it will come down to personal opinion (and whether you're trying to level up on bards) as to whether it's "Grats to the devs on outdoing live!" or "Boo it's not classic!"
Since they never worked in any era, the classic argument is a little moot. Bards, like boats, were something no one ever cared enough to fix, not broken by design. It adds a bit of posterity that they do work here.
