I agree about Maynard being the least important element. I used to view it as the exact opposite, but over the years, I've really come to appreciate Justin and Danny the most. I love Adam's visuals as well, but let's be honest, Danny is the driving force of the band at this point.
I had the pleasure of seeing Tool for the first time on their 2009 tour, and it was a pretty standard setlist. I'm glad to see they're finally changing it up - even if Maynard is sending a pretty obvious message to the fans.
I've got my fingers crossed that I'll get to hear an extra song or two at the Atlanta date, since its the last day of the tour.
