After you pass the 50% mark of mitigation, Improved finish is straight-up better, but it's quite difficult to reach that 50%.
Curing Waltz is indeed nice in a pinch but that's about it. I can never get the party to stack up for it and if I'm having to use it, it usually means the healers are dead and we'll die anyway.

Improvisation is straight up basically never usable unless you want the tiny regen. When do you have time to channel it in the vast majority of fights?
