Agreed. I kind of hoped that they would have acknowledged the 20th of TOT this year on tour. Not a full-blown anniversary where they play the whole album, like they have done with SFAM and I&W. But an acknowledgement by playing 2-3 songs. I'm guessing the band just didn't pick up on this being the 20th this year. But hopefully, those make a comeback, and I would love to see them back to back. For that album as a whole, As I Am and Endless Sacrifice have recirculated a few times, so I don't have a strong desire to see them again (although ES was an unexpected highlight for me this tour). HTF and Vacant haven't been played much at all, and I don't know whether the band has any desire to play them. TDS will likely surface if/when the band does the 12SS, as hinted at. So SOC/ITNOG would be a great combo, IMO.
For me personally, I would love a set that includes TGP, SOC, ITNOG, Octavarium, Forsaken, and Outcry. If I thought James could really bring the power and range, I would add Metropolis and Home to that, but I just don't think that doing those songs proper justice is in his wheelhouse.
