Enchanter/shaman haste does not stack and tbh, the bard "song" hastes are crappy aside from relicI played a bard on live too and was a little surprised about the changes. But I've accepted them now and actually prefer some of them. My only real complaint is that with the 2 positive songs, well, by default one of those spots is taken up by haste (because a)it's a good song to play, and b)if you don't play it people get crabby), which pretty much leaves just 1 song.
