No, it's yet another update where Bards get nothing. In fact the last level of the new champ spawn doesn't even allow Provoke attempts actively discriminating against them. Nothing in any of the Shadowguard encounter is useful to Provoke either. About the only room where it's marginally useful is Belfry where you can Discord a dragon, and use Despair on it for about 3 seconds until it stops your bard song with it's breath or pushes you off the edge. Won't kill it like this though so it's useless.
