I hope they bring back some ATS Songs. Wretches and Kings (maybe as opener) and rotate BITS and Blackout.
HT songs would be great, too. But I'm not so excited about that, because Chester wouldn't sound so great I think. (especially on By Myself, Forgotten).
Drop the Ballad Medley and bring back LOATR, SOTD, Iridescent as full versions (one per set).
