...which I never enjoyed using as a bard, so no loss to me. But regarding the errata, StreamOfTheSky, you didn't use your limited per day class feature to heal a whopping 13 hp with a cantrip. You used it after a fight, when everyone was wounded, to make ALL your cantrips do a whopping 13 HP. So if you needed to do 130 hit points of healing spread out of your 5 allies, you would sing the Healing Hymn, then cast 10 cure minor cantrips, and all the castings would benefit from that one song. Thus, 10 cure minor spells which would normally heal 10 points would instead heal 130 points.
That was always worth it in my campaigns, where the DM made every combat pretty tough. We needed healing after fighting. My bard was much-praised for the Healing Hymn. However, now with the errata, it feels utterly stupid -- "Hey guys, look, I gave up class features to get an alternative feature that doesn't actually do anything."
Ugh.
If they wanted to nix the cantrip trick, why did they castrate its use on all the non-cantrip spells? Man, they could have even relied on the wording in the feature itself -- it says that it adds to your healing spell's dice roll, yet cure minor has no dice roll, so they could say it didn't apply. Why did they have to use a stupid solution instead of an eloquent one?!? Grrr.
