I think she should wait until she has more hits (some more upbeat ones) and she is confident enough to slay the audience left and right because she can.
After all millions of people pay to see her shows and she got good ratings when her concerts were on TV.
She is the right person to do it. Just not right now
The setlist would be:
-Hello
-New lead single
-Rumour Has It / Send My Love / Counting Stars ft Ryan Tedder ^ it was a good idea
-Skyfall
-Make You Feel My Love
-Someone Like You
-Set Fire To The Rain
-Rolling In The Deep
