I'm only going to 1 show for the European tour, so I'm quite happy about the stability of the set list - I know what I'm getting so I can just relax and enjoy the show and focus on the performance.
I went to Pearl Jam and I had a shortlist of what I wanted, some I got, some I didn't, and spent all night wondering what is next.
It would certainly be nice from a bootleg point of view to have some more variety, but for the majority of people that go to only 1 show per tour it's not such an issue
