I agree with Iae. Although I was frustrated at the class change at first, it was mostly a resistance to change overall. The changes were positive. Bards are still a GREAT all-around balanced class, and fun to play.
One thing to note, since I don't know when you left: when melodies initially went in, three beneficial songs would automatically refresh in your melody and you could sing one detrimental song on a target: no twisting involved. This was shortly changed to having two beneficial songs automatically refresh in melody, and you can sing one detrimental song on a target and have it pulse, or you can twist two.
I don't know if you stuck around long enough to see that change, but yes, you can twist, and yes, the DoT damage was increased to compensate, and yes, in the end it's better for the class overall.
