Well I'm of mixed opinion. I think she doesn't do a GREAT job, like she used to sound pretty much the same on a lot of old shows, but her voice has improved live (range, etc) although sometimes it doesn't seem that way ... HOWEVER, The way she's going, performing while her voice isn't in good shape, due to sickness, or tiredness or whatever, will ruin it. I definitely agree she needs vocal coaching to help her support her vocals more.

And on the subject of her "quitting" in November, I highly doubt it, She's said in numerous interviews about the third album, or writing new material. Tim said he's not going anywhere, and Terry doesn't appear to be either.
Aaaand, I know she's said a few times about the band not being around in the future, but I don't see it happening within the next 4-5 years. Maybe after the next album, who knows.
We'll just see what happens in the next Evanescence era. I just pray they make a smush of Origin/pre-fallen songs + songs like The Only One/Your Star for the next record.
